  "message": "[PATCH] blk: remove blk_queue_tag-\u003ereal_max_depth optimization\n\nblk_queue_tag-\u003ereal_max_depth was used to optimize out unnecessary\nallocations/frees on tag resize.  However, the whole thing was very broken -\ntag_map was never allocated to real_max_depth resulting in access beyond the\nend of the map, bits in [max_depth..real_max_depth] were set when initializing\na map and copied when resizing resulting in pre-occupied tags.\n\nAs the gain of the optimization is very small, well, almost nill, remove the\nwhole thing.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nAcked-by: Jens Axboe \u003caxboe@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
