Subject: [SCSI] remove REQ_SPECIAL in scsi_init_io()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=beb6617d994161a6b12c5f69afc6fb154f085447;p=openwrt%2Fstaging%2Fblogic.git

[SCSI] remove REQ_SPECIAL in scsi_init_io()

scsi_init_io() used to set REQ_SPECIAL when it fails sg
allocation before requeueing the request by returning
BLKPREP_DEFER.  REQ_SPECIAL is being updated to mean special
requests.  So, remove REQ_SPECIAL setting.
