+Description: lst: check # of remained RPCs before aborting
+Details : lstcon_rpc_trans_postwait() calls lstcon_rpc_trans_abort() only
+ when the transaction is timeout, so if we got "end_session" to
+ interrupt waiting on transaction, then we can hit the assertion
+ failure ASSERTION(crpc->crp_stamp != 0)

+Description: Adding WIRE_ATTR attribute to LNET types
+Details : LST nodes on different platforms might not communicate well
+ due to the lack of WIRE_ATTR attribute in some LNET structures

+Description: open-unlinked directories trigger MDS LBUG
+Details : Fix regression introduced by the patch from bug 19640.
+ ext3_inc_count() can reset nlink to 1 when the directory
+ is indexed and inode->i_nlink == 2. Work around the problem
+ by incrementing nlink by 2 instead of 1.

+Description: Reconnects are not throttled

+Description: Console flooded with error message from ll_inode_from_lock()

+Description: the readahead code can sleep on a semaphore while holding a
+ spinlock
+Details : in ras_update, "lov_get_info" could be called during increasing
+ readahead windows, which tries to get the mutex lock "lov_lock"
+ while holding the spin_lock "ras_lock", then causes system

+Bugzilla : 20373
+Description: don't do rep-ack if not created anything
+Details : mds_open currently always put a lock into a rep-ack regardless
+ if something was created or not. This is pointless and only
+ creates needless contention. In fact the entire idea was to do
+ this for real creates as a recovery protection.

+Bugzilla : 22187
+Description: properly handle null value for setattr -n lustre.lov
+Details : Running "setfattr -n trusted.lov ." causes a NULL dereference
+ in ll_setxattr() due to no checking if "value" is NULL.

+Description: stack overflow on lock cancellation due to fsync call
+Details : sync_on_lock_cancel is needed for recovery when async journal
+ is enabled, but we actually just need to make sure that
+ metadata blocks have hit the journal, so doing a fs sync
+ should be enough and should consume less stack (just create an
+ empty handle and commmit it).
