It blocks the scsi\_eh thread until the fc\_rport leaves the FC\_PORTSTATE\_BLOCKED, or the fast\_io\_fail\_tmo fires. This is necessary to avoid the scsi\_eh failing recovery actions for blocked rports which would lead to offlined SCSI devices. ## RETURN 0 if the fc\_rport left the state FC\_PORTSTATE\_BLOCKED. FAST\_IO\_FAIL if the fast\_io\_fail\_tmo fired, this should be passed back to scsi\_eh. ## AUTHORS **James Bottomley** \ Author. **Rob Landley** \ Author. ## COPYRIGHT
