      block: rename bio bi_rw to bi_opf · 1eff9d32
      Jens Axboe authored
      Since commit 63a4cc24, bio->bi_rw contains flags in the lower
      portion and the op code in the higher portions. This means that
      old code that relies on manually setting bi_rw is most likely
      going to be broken. Instead of letting that brokeness linger,
      rename the member, to force old and out-of-tree code to break
      at compile time instead of at runtime.
      No intended functional changes in this commit.

      block: make generic_make_request handle arbitrarily sized bios · 54efd50b
      Kent Overstreet authored
      The way the block layer is currently written, it goes to great lengths
      to avoid having to split bios; upper layer code (such as bio_add_page())
      checks what the underlying device can handle and tries to always create
      bios that don't need to be split.
      But this approach becomes unwieldy and eventually breaks down with
      stacked devices and devices with dynamic limits, and it adds a lot of
      complexity. If the block layer could split bios as needed, we could
      eliminate a lot of complexity elsewhere - particularly in stacked
      drivers. Code that creates bios can then create whatever size bios are
      convenient, and more importantly stacked drivers don't have to deal with
      both their own bio size limitations and the limitations of the
      (potentially multiple) devices underneath them.  In the future this will
      let us delete merge_bvec_fn and a bunch of other code.
      We do this by adding calls to blk_queue_split() to the various
      make_request functions that need it - a few can already handle arbitrary
      size bios. Note that we add the call _after_ any call to
      blk_queue_bounce(); this means that blk_queue_split() and
      blk_recalc_rq_segments() don't need to be concerned with bouncing
      affecting segment merging.
      Some make_request_fn() callbacks were simple enough to audit and verify
      they don't need blk_queue_split() calls. The skipped ones are:
       * nfhd_make_request (arch/m68k/emu/nfblock.c)
       * axon_ram_make_request (arch/powerpc/sysdev/axonram.c)
       * simdisk_make_request (arch/xtensa/platforms/iss/simdisk.c)
       * brd_make_request (ramdisk - drivers/block/brd.c)
       * mtip_submit_request (drivers/block/mtip32xx/mtip32xx.c)
       * loop_make_request
       * null_queue_bio
       * bcache's make_request fns
      Some others are almost certainly safe to remove now, but will be left
      for future patches.

      block: add a bi_error field to struct bio · 4246a0b6
      Christoph Hellwig authored
      Currently we have two different ways to signal an I/O error on a BIO:
       (1) by clearing the BIO_UPTODATE flag
       (2) by returning a Linux errno value to the bi_end_io callback
      The first one has the drawback of only communicating a single possible
      error (-EIO), and the second one has the drawback of not beeing persistent
      when bios are queued up, and are not passed along from child to parent
      bio in the ever more popular chaining scenario.  Having both mechanisms
      available has the additional drawback of utterly confusing driver authors
      and introducing bugs where various I/O submitters only deal with one of
      them, and the others have to add boilerplate code to deal with both kinds
      of error returns.
      So add a new bi_error field to store an errno value directly in struct
      bio and remove the existing mechanisms to clean all this up.

      Drivers: block: remove __dev* attributes. · 8d85fce7
      Greg Kroah-Hartman authored
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*

      This change removes the use of __devinit, __devexit_p, __devinitdata,
      __devinitconst, and __devexit from these drivers.
      Based on patches originally written by Bill Pemberton, but redone by me
      in order to handle some of the coding style issues better, by hand.

      block: unify flags for struct bio and struct request · 7b6d91da
      Christoph Hellwig authored
      Remove the current bio flags and reuse the request flags for the bio, too.
      This allows to more easily trace the type of I/O from the filesystem
      down to the block driver.  There were two flags in the bio that were
      missing in the requests:  BIO_RW_UNPLUG and BIO_RW_AHEAD.  Also I've
      renamed two request flags that had a superflous RW in them.
      Note that the flags are in bio.h despite having the REQ_ name - as
      blkdev.h includes bio.h that is the only way to go for now.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      The script does the followings.
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
      The conversion was done in the following steps.
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
      6. percpu.h was updated not to include slab.h.
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      umem: fix request_queue lock warning · f3c737de
      Sage Weil authored
      The umem driver issues two warnings on boot, due to blk_plug_device() and
      blk_remove_plug() being called without q->queue_lock held.  Starting with
      e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions
      warn if q->queue_lock doesn't appear to be locked.  In fact, q->queue_lock
      is NULL (though that apparently isn't otherwise a problem as the driver is
      using card->lock for everything).
      Although blk_init_queue() with take a request_fn_proc and spinlock_t*,
      there isn't a corresponding init helper that takes a make_request_fn.
      Setting queue_lock to &card->lock explicitly seems to work fine for me.
      The warning goes away and the device appears to behave.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      Tim Schmielau authored
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
      recently, it makes sense again to remove other superfluous sched.h includes.
      There are quite a lot of files which include it but don't actually need
      anything defined in there.  Presumably these includes were once needed for
      macros that used to live in sched.h, but moved to other header files in the
      course of cleaning it up.
      To ease the pain, this time I did not fiddle with any header files and only
      removed #includes from .c-files, which tend to cause less trouble.
      Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
      arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
      allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
      configs in arch/arm/configs on arm.  I also checked that no new warnings were
      introduced by the patch (actually, some warnings are removed that were emitted
      by unnecessarily included header files).
