Hi all, In preparation for atomic extent swapping and the online repair functionality that wants atomic extent swaps, enhance the BUI code so that we can support deferred work on the extended attribute fork and on unwritten extents. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=expand-bmap-intent-usage xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=expand-bmap-intent-usage --- fs/xfs/libxfs/xfs_bmap.c | 49 ++++++++++++++++++++-------------------------- fs/xfs/libxfs/xfs_bmap.h | 4 ++-- fs/xfs/xfs_bmap_util.c | 8 ++++---- fs/xfs/xfs_reflink.c | 8 ++++---- 4 files changed, 31 insertions(+), 38 deletions(-)
