NAME

6       fc_block_scsi_eh - Block SCSI eh thread for blocked fc_rport
7

SYNOPSIS

9       int fc_block_scsi_eh(struct scsi_cmnd * cmnd);
10

ARGUMENTS

12       cmnd
13           SCSI command that scsi_eh is trying to recover
14

DESCRIPTION

16       This routine can be called from a FC LLD scsi_eh callback. It blocks
17       the scsi_eh thread until the fc_rport leaves the FC_PORTSTATE_BLOCKED,
18       or the fast_io_fail_tmo fires. This is necessary to avoid the scsi_eh
19       failing recovery actions for blocked rports which would lead to
20       offlined SCSI devices.
21

RETURNS

23       0 if the fc_rport left the state FC_PORTSTATE_BLOCKED. FAST_IO_FAIL if
24       the fast_io_fail_tmo fired, this should be passed back to scsi_eh.
