Yi Zou 37d7b34f05 block: rate-limit the error message from failing commands ... When performing a cable pull test w/ active stress I/O using fio over a dual port Intel 82599 FCoE CNA, w/ 256LUNs on one port and about 32LUNs on the other, it is observed that the system becomes not usable due to scsi-ml being busy printing the error messages for all the failing commands. I don't believe this problem is specific to FCoE and these commands are anyway failing due to link being down (DID_NO_CONNECT), just rate-limit the messages here to solve this issue. v2->v1: use __ratelimit() as Tomas Henzl mentioned as the proper way for rate-limit per function. However, in this case, the failed i/o gets to blk_end_request_err() and then blk_update_request(), which also has to be rate-limited, as added in the v2 of this patch. v3-v2: resolved conflict to apply on current 3.6-rc3 upstream tip.
