+Subject: dlm: initialize file_lock struct in GETLK before copying conflicting lock
+
+From: Jeff Layton <jlayton@redhat.com>
+
+commit 20d5a39929232a715f29e6cb7e3f0d0c790f41eb upstream.
+
+dlm_posix_get fills out the relevant fields in the file_lock before
+returning when there is a lock conflict, but doesn't clean out any of
+the other fields in the file_lock.
+
+When nfsd does a NFSv4 lockt call, it sets the fl_lmops to
+nfsd_posix_mng_ops before calling the lower fs. When the lock comes back
+after testing a lock on GFS2, it still has that field set. This confuses
+nfsd into thinking that the file_lock is a nfsd4 lock.
+
+Fix this by making DLM reinitialize the file_lock before copying the
+fields from the conflicting lock.

+Subject: sata_nv: ck804 has borked hardreset too
+
+From: Tejun Heo <tj@kernel.org>
+
+commit 8d993eaa9c3c61b8a5929a7f695078a1fcfb4869 upstream.
+
+While playing with nvraid, I found out that rmmoding and insmoding
+often trigger hardreset failure on the first port (the second one was
+always okay).  Seriously, how diverse can you get with hardreset
+behaviors?  Anyways, make ck804 use noclassify variant too.

+nv_nf2_hardreset() will be used by other flavors too.  Rename it to
