      Merge tag 'xfs-for-linus-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs · 661b99e9
      Linus Torvalds authored
      Pull xfs fixes from Dave Chinner:
       "This update fixes a warning in the new pagecache_isize_extended() and
        updates some related comments, another fix for zero-range
        misbehaviour, and an unforntuately large set of fixes for regressions
        in the bulkstat code.
        The bulkstat fixes are large but necessary.  I wouldn't normally push
        such a rework for a -rcX update, but right now xfsdump can silently
        create incomplete dumps on 3.17 and it's possible that even xfsrestore
        won't notice that the dumps were incomplete.  Hence we need to get
        this update into 3.17-stable kernels ASAP.
        In more detail, the refactoring work I committed in 3.17 has exposed a
        major hole in our QA coverage.  With both xfsdump (the major user of
        bulkstat) and xfsrestore silently ignoring missing files in the
        dump/restore process, incomplete dumps were going unnoticed if they
        were being triggered.  Many of the dump/restore filesets were so small
        that they didn't evenhave a chance of triggering the loop iteration
        bugs we introduced in 3.17, so we didn't exercise the code
        sufficiently, either.
        We have already taken steps to improve QA coverage in xfstests to
        avoid this happening again, and I've done a lot of manual verification
        of dump/restore on very large data sets (tens of millions of inodes)
        of the past week to verify this patch set results in bulkstat behaving
        the same way as it does on 3.16.
        Unfortunately, the fixes are not exactly simple - in tracking down the
        problem historic API warts were discovered (e.g xfsdump has been
        working around a 20 year old bug in the bulkstat API for the past 10
        years) and so that complicated the process of diagnosing and fixing
        the problems.  i.e. we had to fix bugs in the code as well as
        discover and re-introduce the userspace visible API bugs that we
        unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly.
         - incorrect warnings about i_mutex locking in pagecache_isize_extended()
           and updates comments to match expected locking
         - another zero-range bug fix for stray file size updates
         - a bunch of fixes for regression in the bulkstat code introduced in

      tiny: rename ENABLE_DEV_COREDUMP to ALLOW_DEV_COREDUMP · cd3d9ea1
      Johannes Berg authored
      The ENABLE_DEV_COREDUMP option is misleading as it implies that
      it gets the framework enabled, this isn't true it just allows it
      to get enabled if a driver needs it.
      Rename it to ALLOW_DEV_COREDUMP to better capture its semantics.

      sysfs: driver core: Fix glue dir race condition by gdp_mutex · e4a60d13
      Yijing Wang authored
      There is a race condition when removing glue directory.
      It can be reproduced in following test:
      path 1: Add first child device
                  /*find parent from glue_dirs.list*/
                  list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry)
                          if (k->parent == parent_kobj) {
                                  kobj = kobject_get(k);
      path2: Remove last child device under glue dir
      If path2 has been called cleanup_glue_dir(), but not
      call kobject_put(glue_dir), the glue dir is still
      in parent's kset list. Meanwhile, path1 find the glue
      dir from the glue_dirs.list. Path2 may release glue dir
      before path1 call kobject_get(). So kernel will report
      the warning and bug_on.
      This is a "classic" problem we have of a kref in a list
      that can be found while the last instance could be removed
      at the same time.
      This patch reuse gdp_mutex to fix this race condition.
      The following calltrace is captured in kernel 3.4, but
      the latest kernel still has this bug.

      MIPS: Fix build with binutils 2.24.51+ · 842dfc11
      Manuel Lauss authored
      Starting with version MIPS binutils complain loudly
      about mixing soft-float and hard-float object files, leading to this
      build failure since GCC is invoked with "-msoft-float" on MIPS:
      {standard input}: Warning: .gnu_attribute 4,3 requires `softfloat'
        LD      arch/mips/alchemy/common/built-in.o
      mipsel-softfloat-linux-gnu-ld: Warning: arch/mips/alchemy/common/built-in.o
       uses -msoft-float (set by arch/mips/alchemy/common/prom.o),
       arch/mips/alchemy/common/sleeper.o uses -mhard-float
      To fix this, we detect if GAS is new enough to support "-msoft-float" command
      option, and if it does, we can let GCC pass it to GAS;  but then we also need
      to sprinkle the files which make use of floating point registers with the
      necessary ".set hardfloat" directives.
