Setting PA_PWRMode using DME_SET triggers the power mode change. And then the result will be given by the HCS.UPMCRS. This operation should be done atomically. Signed-off-by:

IACTH(Interrupt aggregation counter threshold) value is allowed up to 0x1F and current setting value is the maximum. This value is related with NUTRS(max:0x20) of HCI's capability. Considering HCI controller doesn't support the maximum, IACTH setting should be adjusted with possible value. For that, existing 'ufshcd_config_int_aggr' is split into two part [reset, configure].

Unlike 'GOOD' and 'CHECK CONDITION', other status values in Response UPIU may or may not contain sense data. That is returning sense data isn't obvious. So, in this case the Data Segment Length field should be checked. If a non-zero value, it means that UPIU has Sense Data in the Data Segment area. Signed-off-by:

Right now the Makefile for the mpt3sas driver does not even allow the driver to be built into the kernel. So fix that up, as there doesn't seem to be any obvious reason why this shouldn't be done. Signed-off-by:

This fixes an issue seen with devices getting marked offline in a scenario where a VIOS was getting rebooted while a client VFC adapter is in SCSI EH and prevents unnecessary EH escalation in some scenarios. Signed-off-by:

Push file descriptor list locking down to per-device locking. Let sg_index_lock only protect device lookup. sdp->detached is also set and checked with this lock held. Signed-off-by:

@detached is set under the protection of sg_index_lock. Without getting the lock, new sfp will be added during sg removal and there is no chance for it to be picked out. So check with sg_index_lock held in sg_add_sfp(). Signed-off-by:

Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock. @exclude is used to record which type of rwsem we are holding. Signed-off-by:

Vaughan Cao authored
A race condition may happen if two threads are both trying to open the same sg with O_EXCL simultaneously. It's possible that they both find fsds list is empty and get_exclude(sdp) returns 0, then they both call set_exclude() and break out from wait_event_interruptible and resume open. Now use rwsem to protect this process. Exclusive open gets write lock and others get read lock. The lock will be held until file descriptor is closed. This also leads 'exclude' only a status rather than a check mark. Signed-off-by:

Commit b90ebc3d ("[SCSI] scsi_debug: fix logical block provisioning support") fixed several issues with logical block provisioning support, but it still doesn't properly fix the cases when unmap_alignment > 0. For example, load scsi_debug module with the following module parameters and make all blocks mapped by filling the storage with zero. # modprobe scsi_debug lbpu=1 unmap_alignment=1 unmap_granularity=4 # dd if=/dev/zero of=$DEV Then, try to unmap the first unmappable blocks at lba=1, but GET LBA STATUS unexpectedly reports that the last UNMAP has done nothing. # sg_unmap --lba=1 --num=4 $DEV # sg_get_lba_status --lba=1 $DEV descriptor LBA: 0x0000000000000001 blocks: 16383 mapped The problem is in map_index_to_lba(), which should return the first LBA which is corresponding to a given index of provisioning map (map_storep).

With module parameter num_parts > 0, partition table is built on the ramdisk storage when loading the driver. Unfortunately, there is an endianness bug in sdebug_build_parts(). So the partition table is not correctly initialized on big-endian systems. Signed-off-by:
