resolved:\n\nbtrfs: fix the possible bioc_list memory leak during error\n\nThere are two possible ways to leak bioc memory on\nbtrfs_ordered_extent::bioc_list:\n\n- An error occurred for btrfs_insert_one_raid_extent()\n Then the function btrfs_insert_raid_extent() immediately return\n without freeing any bioc in the bioc_list.\n\n- An ordered extent hit an IO error\n In that case the ordered extent will have BTRFS_ORDERED_IOERR set, and\n skip the call on btrfs_insert_raid_extent() completely.\n\nFix the problem by:\n\n- Introduce a new helper, btrfs_cleanup_ordered_bioc_list()\n Which will remove all bioc from the bioc_list, and release the bioc.\n\n- Call the above helper for btrfs_insert_raid_extent()\n So that the cleanup helper is always called no matter what.\n\n- Call the above helper for btrfs_finish_one_ordered()\n This is called just before the final release on the ordered extent.\n\nThis was reported by Sashiko when reviewing another patch."}], "lastModified":
