Subject: [GIT PULL] gfs2 debugfs improvements

Dear Linus,

please consider pulling the following gfs2 changes on top of the pull request
I've sent earlier today.

Commit "gfs2: Add glockfd debugfs file" modifies fs/file.c to export
task_lookup_next_fd_rcu(), and kernel/pid.c to export find_ge_pid().  We use
those two functions to iterate through all processes and their file
descriptors.  I haven't received any pushback to exporting those two functions,
but no affirmation, either.

The merge commit included in this pull request resolves a conflict in
gfs2_inode_lookup(); not sure if you'd rather like to squash this merge and
resolve the conflict directly; in any case, the merge commit shows the desired
end result.

Thank you very much,
Andreas

----------------------------------------------------------------
gfs2 debugfs improvements

- Improve the way how the state of glocks is reported in debugfs
  for glocks which are not held by processes, but rather by other
  resouces like cached inodes or flocks.
