  - btrfs: skip reserved bytes warning on unmount after log cleanup failure After the recent changes made by     commit c2e39305299f01 (btrfs: clear extent buffer uptodate when we fail to write it) and its followup     fix, commit 651740a5024117 (btrfs: check WRITE_ERR when trying to read an extent buffer), we can now end     up not cleaning up space reservations of log tree extent buffers after a transaction abort happens, as     well as not cleaning up still dirty extent buffers. This happens because if writeback for a log tree     extent buffer failed, then we have cleared the bit EXTENT_BUFFER_UPTODATE from the extent buffer and we     have also set the bit EXTENT_BUFFER_WRITE_ERR on it. Later on, when trying to free the log tree with     free_log_tree(), which iterates over the tree, we can end up getting an -EIO error when trying to read a     node or a leaf, since read_extent_buffer_pages() returns -EIO if an extent buffer does not have     EXTENT_BUFFER_UPTODATE set and has the EXTENT_BUFFER_WRITE_ERR bit set. Getting that -EIO means that we     return immediately as we can not iterate over the entire tree. In that case we never update the reserved     space for an extent buffer in the respective block group and space_info object. When this happens we get     the following traces when unmounting the fs: [174957.284509] BTRFS: error (device dm-0) in     cleanup_transaction:1913: errno=-5 IO failure [174957.286497] BTRFS: error (device dm-0) in     free_log_tree:3420: errno=-5 IO failure [174957.399379] ------------[ cut here ]------------     [174957.402497] WARNING: CPU: 2 PID: 3206883 at fs/btrfs/block-group.c:127 btrfs_put_block_group+0x77/0xb0     [btrfs] [174957.407523] Modules linked in: btrfs overlay dm_zero (...)
