* [SCSI] Allow MPT Fusion SAS 3.0 driver to be built into the kernelGreg Kroah-Hartman2013-09-061-1/+1
| | | | | | | | | | 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.

* [SCSI] sg: use rwsem to solve race during exclusive openVaughan Cao2013-09-031-38/+41
| | | | | | | | | | | | | | | 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.

* [SCSI] scsi_debug: fix logical block provisioning support when ↵Akinobu Mita2013-09-031-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unmap_alignment != 0 Commit b90ebc3d5c41c9164ae04efd2e4f8204c2a186f1 ("[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.
