      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
