      VFS: we need to set LOOKUP_JUMPED on mountpoint crossing · a3fbbde7
      Al Viro authored
      Mountpoint crossing is similar to following procfs symlinks - we do
      not get ->d_revalidate() called for dentry we have arrived at, with
      unpleasant consequences for NFS4.
      Simple way to reproduce the problem in mainline:
          cat >/tmp/a.c <<'EOF'
          #include <unistd.h>
          #include <fcntl.h>
          #include <stdio.h>
                  struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
                  if (fcntl(0, F_SETLK, &fl))
          cc /tmp/a.c -o /tmp/test
      then on nfs4:
          mount --bind file1 file2
          /tmp/test < file1		# ok
          /tmp/test < file2		# spews "setlk: No locks available"...
      What happens is the missing call of ->d_revalidate() after mountpoint
      crossing and that's where NFS4 would issue OPEN request to server.
      The fix is simple - treat mountpoint crossing the same way we deal with
      following procfs-style symlinks.  I.e.  set LOOKUP_JUMPED...

      PM / devfreq: fix private_data · 1a51cfdc
      Jonathan Corbet authored
      The "private_date" field in struct devfreq_dev_status almost certainly
      wants to be "private_data"; since there are no in-tree users of this
      functionality, now seems like an easy time to make the fix.

      Dominik Brodowski authored
      Since commit 4a31a334, the name of this misc device is not initialized,
      which leads to a funny device named /dev/(null) being created and
      /proc/misc containing an entry with just a number but no name. The latter
      leads to complaints by cryptsetup, which caused me to investigate this

      ARM: OMAP: Fix export.h or module.h includes · a1bcc1dc
      Tony Lindgren authored
      Commit 32aaeffb (Merge branch
      'modsplit-Oct31_2011'...) caused some build errors. Fix these
      and make sure we always have export.h or module.h included
      for MODULE_ and EXPORT_SYMBOL users:
      $ grep -rl ^MODULE_ arch/arm/*omap*/*.c | xargs \
        grep -L linux/module.h
      Also check we either have export.h or module.h included
      for the files exporting symbols:
      $ grep -rl EXPORT_SYMBOL arch/arm/*omap*/*.c | xargs \
        grep -L linux/export.h | xargs grep -L linux/module.h

      forcedeth: Improve stats counters · 0bdfea8b
      Mandeep Baines authored
      Rx byte count was off; instead use the hardware's count.  Tx packet
      count was counting pre-TSO packets; instead count on-the-wire packets.
      Report hardware dropped frame count as rx_fifo_errors.
      - The count of transmitted packets reported by the forcedeth driver
        reports pre-TSO (TCP Segmentation Offload) packet counts and not the
        count of the number of packets sent on the wire. This change fixes
        the forcedeth driver to report the correct count. Fixed the code by
        copying the count stored in the NIC H/W to the value reported by the
      - Count rx_drop_frame errors as rx_fifo_errors:
        We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
        for too long.  Normally, rx_fifo_errors would be counted in this case.
        The rx_drop_frame error count is private to forcedeth and is not
        reported by ifconfig or sysfs.  The rx_fifo_errors count is currently
        unused in the forcedeth driver.  It is reported by ifconfig as overruns.
        This change reports rx_drop_frame errors as rx_fifo_errors.
