  "message": "xfs: use b_maps[] for discontiguous buffers\n\nCommits starting at 77c1a08 introduced a multiple segment support\nto xfs_buf. xfs_trans_buf_item_match() could not find a multi-segment\nbuffer in the transaction because it was looking at the single segment\nblock number rather than the multi-segment b_maps[0].bm.bn. This\nresults on a recursive buffer lock that can never be satisfied.\n\nThis patch:\n 1) Changed the remaining b_map accesses to be b_maps[0] accesses.\n 2) Renames the single segment b_map structure to __b_map to avoid\n    future confusion.\n\nSigned-off-by: Mark Tinguely \u003ctinguely@sgi.com\u003e\nReviewed-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Ben Myers \u003cbpm@sgi.com\u003e\n\n",
