This patch set includes several bug fixes and patches for enabling
clustering support for scsi_debug.
The reason why I would like to enable clustering is to test commands
with huge transfer length. Without enabling clustering support, the
transfer length for read and write scsi commands is limited upto 8MB
when page size is 4KB and sg_tablesize is 2048
(= SCSI_MAX_SG_CHAIN_SEGMENTS).
Changes from v1:
- remove unnecessary irqsave/irqrestore while iterating sg mapping
- protect device access with atomic_rw lock
- make clustering module parameter writable
Akinobu Mita (7):
scsi_debug: fix false positive logical block reference tag check fail
scsi_debug: make pseudo_primary static
scsi_debug: fix duplicate dif_errors increment
scsi_debug: fix resp_xdwriteread() return value when running out of
memory
scsi_debug: prepare to enable clustering
scsi_debug: protect device access with atomic_rw lock
scsi_debug: add ability to enable clustering
