Vasu Dev a0cc1ecc09 [SCSI] libfc: fix a circular locking warning during sending RRQ ... Currently the fc_exch_rrq is called with fc_exch's ex_lock held. The fc_exch_rrq allocates new exch and that requires taking ex_lock again after EM lock. This locking order causes warning, see more details on this warning at :- http://www.open-fcoe.org/pipermail/devel/2009-July/003251.html This patch fixes this by dropping the ex_lock before calling fc_exch_rrq(). The fc_exch_rrq needs to grab ex_lock lock again to schedule RRQ retry and in the meanwhile fc_exch_reset could occur before ex_lock is grabbed inside fc_exch_rrq. So to handle this case, this patch adds additional check to detect fc_exch_reset after ex_lock acquired and in case the fc_exch_reset occurred then abandons the RRQ retry and releases the exch.
