+Subject: libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8 (2BA30001)
+
+From: Michele Baldessari <michele@acksyn.org>
+
+commit b28a613e9138e4b3a64649bd60b13436f4b4b49b upstream.
+
+Via commit 87809942d3fa "libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk
+for Seagate Momentus SpinPoint M8" we added a quirk for disks named
+"ST1000LM024 HN-M101MBB" with firmware revision "2AR10001".
+
+As reported on https://bugzilla.redhat.com/show_bug.cgi?id=1073901,
+we need to also add firmware revision 2BA30001 as it is broken as well.

+Subject: NFS: Fix a delegation callback race
+
+From: Trond Myklebust <trond.myklebust@primarydata.com>
+
+commit 755a48a7a4eb05b9c8424e3017d947b2961a60e0 upstream.
+
+The clean-up in commit 36281caa839f ended up removing a NULL pointer check
+that is needed in order to prevent an Oops in
+nfs_async_inode_return_delegation().
+
+Reported-by: "Yan, Zheng" <zheng.z.yan@intel.com>
+Link: http://lkml.kernel.org/r/5313E9F6.2020405@intel.com
+Fixes: 36281caa839f (NFSv4: Further clean-ups of delegation stateid validation)
