      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>
          main()
          {
                  struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
                  if (fcntl(0, F_SETLK, &fl))
                          perror("setlk");
          }
          EOF
          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...

      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
        arch/arm/mach-omap2/dsp.c
        arch/arm/mach-omap2/mailbox.c
        arch/arm/mach-omap2/omap-iommu.c
        arch/arm/mach-omap2/smartreflex.c
      
      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
        driver.
      
      - 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.

      forcedeth: remove unneeded stats updates · 4687f3f3
      david decotigny authored
      
      
      Function ndo_get_stats() updates most of the stats from hardware
      registers, making the manual updates un-needed. This change removes
      these manual updates. Main exception is rx_missed_errors which needs
      manual update.
      
      Another exception is rx_packets, still updated manually in this commit
      to make sure this patch doesn't change behavior of driver. This will
      be addressed by a future patch.

      Mike Ditto authored
      
      
      This is to avoid a race, accidentally acknowledging an interrupt that
      we didn't notice and won't immediately process.  This is based solely
      on code inspection; it is not known if there was an actual bug here.
