ocfs2: Disable CATCH_BH_JBD_RACES
Commit aa20775d1e7feba9b22e761fa9b69bd5c3f043bd fixed a race
related to NFS and its backdoor access to inodes via ocfs2_get_dentry().
In the fix, we do a dirty read of the inode to get the suballoc_slot
and bit.
We suspect that this dirty read is racing ocfs2_remove_inode() which
removes the inode from the cache before commiting the transaction. Meaning
the dirty read will read from disk while that block is still in JBD cache.
In normal course this should never happen. But this is an exception.
This patch disables the CATCH_BH_JBD_RACES which BUGs when it encounters
the above condition. This piece of code was added in pre-1.0 days when
we were adding JBD support in OCFS2. I don't recall us ever encountering
this BUG before.
Potentially fixes ossbz#1235
