[PATCH 1/1] OCFS2: anti stale inode for nfs (V6)
...ually we have to read out the inode in question from disk(not cache) first
to know its alloc slot(tells alloc inode) and allot bit(tells alloc group). and
if its not stale(by above logic) we read it out using ocfs2_iget(). the second
read should from cache.
and also we have to add a per superblock nfs_sync_lock to cover the lock for
alloc inode and that for inode in question. this is because ocfs2_get_dentry()
and ocfs2_delete_inode() lock on them in reverse order. nfs_sync_lock is locked
in EX mode in ocfs2_get_dentry() and in PR mode in ocfs2_delete_inode(). so
that mutliple ocfs2_delete_inode() can run...

[git patches] Ocfs2 updates for 2.6.30
Hi,
The following patches comprise the bulk of Ocfs2 updates for the
2.6.30 merge window. Aside from larger, more involved fixes, we're adding
the following features, which I will describe in the order their patches are
mailed.
Sunil's exported some more state to our debugfs files, and
consolidated some other aspects of our debugfs infrastructure. This will
further aid us in debugging
