Subject: [SCSI] libiscsi: Use SCSI_MLQUEUE_TARGET_BUSY
X-Git-Tag: v2.6.28-rc1~263^2~35
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=d6d13ee19da6d291c99f980dcb76f6b7dc676804;p=linux-2.6-omap-h63xx.git

[SCSI] libiscsi: Use SCSI_MLQUEUE_TARGET_BUSY

For the conditions below we do not want the queuecommand
function to call us right back, so return SCSI_MLQUEUE_TARGET_BUSY.
