The rest are just some cleanups or enhancements. V2: Updated patch 10/11, it mentioned a no longer existing argument that removed in patch 05/11, the patches were re-ordered at some point. Filipe Manana (11): btrfs: fix race with memory mapped writes when activating swap file btrfs: fix swap file activation failure due to extents that used to be shared btrfs: allow swap activation to be interruptible btrfs: avoid monopolizing a core when activating a swap file btrfs: remove no longer needed strict argument from can_nocow_extent() btrfs: remove the snapshot check from check_committed_ref() btrfs: avoid redundant call to get inline ref type at check_committed_ref() btrfs: simplify return logic at check_committed_ref() btrfs: simplify arguments for btrfs_cross_ref_exist() btrfs: add function comment for check_committed_ref() btrfs: add assertions and comment about path expectations to btrfs_cross_ref_exist() fs/btrfs/btrfs_inode.h | 2 +- fs/btrfs/direct-io.c | 3 +- fs/btrfs/extent-tree.c | 128 +++++++++++++++++++++++++----------- fs/btrfs/extent-tree.h | 3 +- fs/btrfs/file.c | 2 +- fs/btrfs/inode.c | 146 +++++++++++++++++++++++++++++------------ fs/btrfs/locking.h | 5 ++ 7 files changed, 203 insertions(+), 86 deletions(-) Reviewed-by: Qu Wenruo
