qla2x00_mem_alloc() returns 1 on success and -ENOMEM on failure. On the one hand the caller assumes non-zero is success but on the other hand the caller also assumes that it returns an error code. I've fixed it to return zero on success and a negative error code on failure. This matches the documentation as well.

isci is needlessly tying libata's hands by returning SAM_STAT_CHECK_CONDITION to some ata errors. Instead, prefer SAS_PROTO_RESPONSE to let libata (via sas_ata_task_done()) disposition the device-to-host fis. For example isci is triggering an HSM Violation where AHCI is showing a simple media error for the same bus condition: isci: ata7.00: failed command: READ VERIFY SECTOR(S) ata7.00: cmd 40/00:01:00:00:00/00:00:00:00:00/e0 tag 0 res 01/04:00:00:00:00/00:00:00:00:00/e0 Emask 0x3 (HSM violation) ahci: ata6.00: failed command: READ VERIFY SECTOR(S) ata6.00: cmd 40/00:01:00:00:00/00:00:00:00:00/e0 tag 0 res 51/40:01:00:00:00/00:00:00:00:00/e0 Emask 0x9 (media error) Note that the isci response matches this from sas_ata_task_done(): /* We saw a SAS error. Send a vague error. */ [..] dev->sata_dev.fis[3] = 0x04; /* status err */ dev->sata_dev.fis[2] = ATA_ERR; The end effect is that isci is needlessly triggering hard resets when they are not necessary.

libsas sometimes short circuits timeouts to force commands into error recovery. It is misleading to log that the command timed-out in sas_scsi_timed_out() when in fact it was just queued for error handling. It's also redundant in the case of a true timeout as libata eh will detect and report timeouts via it's AC_ERR_TIMEOUT facility. Given that some environments consider "timeout" errors to be indicative of impending device failure demote the sas_scsi_timed_out() timeout message to be disabled by default. This parallels ata_scsi_timed_out(). [jejb: checkpatch fix] Reported-by:

SCSI retry delay upon SAM_STAT_BUSY/_SET_FULL was not being handled in bnx2fc. This patch adds such handling by returning TARGET_BUSY to the SCSI ML for the corresponding LUN until the retry timer expires. Signed-off-by:

The problem has been identified to be a change in the scsi_remove_device path where a call to the pm_runtime_set_memalloc_noio was added when del_gendisk is called in this path. Note that the new pm routine attempts to cycle through all parent devices from the FC target device to set the memalloc_noio flag. Because of this new change, a dependency was created between the FC target device and the parent netdev device in the destroy path. In order to synchronized the destroy paths, bnx2fc has been modified to flush all destroy workqueues in the NETDEV_UNREGISTER return path. [ 4.123584] BUG: soft lockup - CPU#8 stuck for 22s!
