From: Ye Bin <yebin10@xxxxxxxxxx> Diff v2 vs v1: 1. Remove set scsi host state by sysfs, as set host state by sysfs may lead to functional issue. Scsi host state has it's own running state machine. 2. Introduce 'blocked' sysfs api for set scsi host blocking IO. Use this function we can do some test.
