+Subject: SCSI: mpt2sas: fix firmware failure with wrong task attribute
+
+From: Sreekanth Reddy <Sreekanth.Reddy@lsi.com>
+
+commit 48ba2efc382f94fae16ca8ca011e5961a81ad1ea upstream.
+
+When SCSI command is received with task attribute not set, set it to SIMPLE.
+Previously it is set to untagged. This causes the firmware to fail the commands.

+Subject: SCSI: zfcp: fix adapter (re)open recovery while link to SAN is down
+
+From: Daniel Hansel <daniel.hansel@linux.vnet.ibm.com>
+
+commit f76ccaac4f82c463a037aa4a1e4ccb85c7011814 upstream.
+
+FCP device remains in status ERP_FAILED when device is switched online
+or adapter recovery is triggered  while link to SAN is down.
+
+When Exchange Configuration Data command returns the FSF status
+FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE it aborts the exchange process.
+The only retries are done during the common error recovery procedure
+(i.e. max. 3 retries with 8sec sleep between) and remains in status
+ERP_FAILED with QDIO down.
+
+This commit reverts the commit 0df138476c8306478d6e726f044868b4bccf411c
+(zfcp: Fix adapter activation on link down).
+When FSF status FSF_EXCHANGE_CONFIG_DATA_INCOMPLETE is received the
+adapter recovery will be finished without any retries. QDIO will be
+up now and status changes such as LINK UP will be received now.

+Subject: SUNRPC: PipeFS MOUNT notification optimization for dying clients
+
+From: Stanislav Kinsbursky <skinsbursky@parallels.com>
+
+commit 4f6bb246f69443549fbbd0f2abaf863243cb35e9 upstream.
+
+Not need to create pipes for dying client. So just skip them.
+
+Note: we can safely dereference the client structure, because notification
+caller is holding sn->pipefs_sb_lock.
