This patch eliminates the reap_ref and replaces it with a proper kref. On last put of this kref, the target is removed from visibility in sysfs. The final call to scsi_target_reap() for the device is done from __scsi_remove_device() and only if the device was made visible. This ensures that the target disappears as soon as the last device is gone rather than waiting until final release of the device (which is often too long). Reviewed-by:

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:
