  "message": "Btrfs: Introduce contexts for metadata reservation\n\nIntroducing metadata reseravtion contexts has two major advantages.\nFirst, it makes metadata reseravtion more traceable. Second, it can\nreclaim freed space and re-add them to the itself after transaction\ncommitted.\n\nBesides add btrfs_block_rsv structure and related helper functions,\nThis patch contains following changes:\n\nMove code that decides if freed tree block should be pinned into\nbtrfs_free_tree_block().\n\nMake space accounting more accurate, mainly for handling read only\nblock groups.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n",
