[PATCH 0/3] kill-the-BKL/reiserfs: reiserfs fixes

[Frederic Weisbecker <fweisbec@gmail.com>]

Ingo,

This small patchset fixes some deadlocks I've faced after trying
some pressures with dbench on a reiserfs partition.

There is still some work pending such as adding some checks to ensure we
_always_ release the lock before sleeping, as you suggested.
Also I have to fix a lockdep warning reported by Alessio Igor Bogani.
And also some optimizations....

Thanks,
Frederic.

  kill-the-BKL/reiserfs: provide a tool to lock only once the write lock
  kill-the-BKL/reiserfs: lock only once in reiserfs_truncate_file
  kill-the-BKL/reiserfs: only acquire the write lock once in
    reiserfs_dirty_inode
