  "message": "raid5: Don\u0027t set read-ahead when there is no queue\n\ndm-raid456 does not provide a \u0027queue\u0027 for raid5 to use,\nso we must make raid5 stop depending on the queue.\n\nFirst: read_ahead\ndm handles read-ahead adjustment fully in userspace, so\nsimply don\u0027t do any readahead adjustments if there is\nno queue.\n\nAlso re-arrange code slightly so all the accesses to -\u003equeue are\ntogether.\n\nFinally, move the blk_queue_merge_bvec function into the \u0027if\u0027 as\nthe -\u003esplit_io setting in dm-raid456 has the same effect.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n",
