Brian King 73ee5d8672 [SCSI] ibmvfc: Fix soft lockup on resume ... This fixes a softlockup seen on resume. During resume, the CRQ must be reenabled. However, the H_ENABLE_CRQ hcall used to do this may return H_BUSY or H_LONG_BUSY. When this happens, the caller is expected to retry later. Normally the H_ENABLE_CRQ succeeds relatively soon. However, we have seen cases where this can take long enough to see softlockup warnings. This patch changes a simple loop, which was causing the softlockup, to a loop at task level which sleeps between retries rather than simply spinning.
