Bug in inode deletion code leading to stale inodes

The question is how to avoid this. It seems to me that we have to really
do open_lock() and not just trylock to avoid...

[PATCH] ocfs2: flush dentry lock drop when sync ocfs2 volume.
In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the

[PATCH 0/5] OCFS2 quota fixes
Hello,
the following series of patches fixes some issues with OCFS2 quotas.
The first patch modifies VFS quota locking, the next patch uses the

The third and the fourth patches fix another possible deadlocks in OCFS2
quota code and the last patch is a minor cleanup.
