6   This routine can be called from a FC LLD scsi_eh callback. It
7   blocks the scsi_eh thread until the fc_rport leaves the
8   FC_PORTSTATE_BLOCKED, or the fast_io_fail_tmo fires. This is
9   necessary to avoid the scsi_eh failing recovery actions for blocked
10   rports which would lead to offlined SCSI devices.
11</p></div><div class="refsect1"><a name="idp1124428628"></a><h2>Returns</h2><p>
12   0 if the fc_rport left the state FC_PORTSTATE_BLOCKED.
13   FAST_IO_FAIL if the fast_io_fail_tmo fired, this should be
14   passed back to scsi_eh.
