+Subject: libata: retry FS IOs even if it has failed with AC_ERR_INVALID
+
+From: Tejun Heo <tj@kernel.org>
+
+commit 534ead709235b967b659947c55d9130873a432c4 upstream.
+
+libata currently doesn't retry if a command fails with AC_ERR_INVALID
+assuming that retrying won't get it any further even if retried.
+However, a failure may be classified as invalid through hardware
+glitch (incorrect reading of the error register or firmware bug) and
+there isn't whole lot to gain by not retrying as actually invalid
+commands will be failed immediately.  Also, commands serving FS IOs
+are extremely unlikely to be invalid.  Retry FS IOs even if it's
+marked invalid.
+
+Transient and incorrect invalid failure was seen while debugging
+firmware related issue on Samsung n130 on bko#14314.

+Subject: svc: Clean up deferred requests on transport destruction
+
+From: Tom Tucker <tom@opengridcomputing.com>
+
+commit 22945e4a1c7454c97f5d8aee1ef526c83fef3223 upstream.
+
+A race between svc_revisit and svc_delete_xprt can result in
+deferred requests holding references on a transport that can never be
+recovered because dead transports are not enqueued for subsequent
+processing.
+
+Check for XPT_DEAD in revisit to clean up completing deferrals on a dead
+transport and sweep a transport's deferred queue to do the same for queued
+but unprocessed deferrals.
