This allows us to return NEEDS_RETRY instead of ADD_TO_MLQUEUE, allowing to terminate the retries after a certain time. At the same time a workqueue item might already be queued, which should be started immediately to avoid any delays.

* scsi_dh_alua: Use workqueue for RTPGHannes Reinecke2016-02-231-54/+242
| | | | | | | | | | | | | | | | | | | | | | | | | The current ALUA device_handler has two drawbacks: - We're sending a 'SET TARGET PORT GROUP' command to every LUN, disregarding the fact that several LUNs might be in a port group and will be automatically switched whenever _any_ LUN within that port group receives the command. - Whenever a LUN is in 'transitioning' mode we cannot block I/O to that LUN, instead the controller has to abort the command. This leads to increased traffic across the wire and heavy load on the controller during switchover. With this patch the RTPG handling is moved to a per-portgroup workqueue. This reduces the number of 'REPORT TARGET PORT GROUP' and 'SET TARGET PORT GROUPS' sent to the controller as we're sending them now per port group, and not per device as previously. It also allows us to block I/O to any LUN / port group found to be in 'transitioning' ALUA mode, as the workqueue item will be requeued until the controller moves out of transitioning.

* lpfc: Add lockdep assertionsJohannes Thumshirn2016-02-232-0/+48
| | | | | | | | | | | Several functions in lpfc have comments stating that the function must be called with the hbalock (or hostlock, or ringlock) held. Add lockdep_assert_held() annotations to these functions, so one can actually verify the locks are held.

* bfa: deinline __bfa_trc() and __bfa_trc32()Denys Vlasenko2016-02-232-37/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __bfa_trc() compiles to 115 bytes of machine code. With this .config: http://busybox.net/~vda/kernel_config there are 1494 calls of __bfa_trc(). __bfa_trc32() is very similar, so it is uninlined too. However, it appears to be unused, therefore this patch ifdefs it out. Change in code size is about 130,000 bytes: text data bss dec hex filename 85975426 22294712 20627456 128897594 7aed23a vmlinux.before 85842882 22294584 20627456 128764922 7accbfa vmlinux [mkp: Removed unused __bfa_trc32()] Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com> Acked-by: Anil Gurumurthy <anil.gurumurthy@qlogic.com> CC: Fabian Frederick <fabf@skynet.be> CC: Anil Gurumurthy <anil.gurumurthy@qlogic.com> CC: Christoph Hellwig <hch@lst.de> CC: Guenter Roeck <linux@roeck-us.net> CC: Ben Hutchings <ben@decadent.org.uk> CC: James Bottomley <JBottomley@Parallels.com> CC: linux-kernel@vger.kernel.org CC: linux-scsi@vger.kernel.org Signed-off-by: Martin K.
