Here's version 2 of the the free space B-tree patches, addressing Josef's review from the last round, which you can find here: http://www.spinics.net/lists/linux-btrfs/msg46713.html
Changes from v1->v2: - Cleaned up a bunch of unnecessary instances of "if (ret) goto out; ret = 0" - Added aborts in the free space tree code closer to the site the error is encountered: where we add or remove block groups, add or remove free space, and also when we convert formats - Moved loading of the free space tree into caching_thread() and added a new patch 4 in preparation for it - Commented a bunch of stuff in the extent buffer bitmap operations and refactored some of the complicated logic - Added sanity tests for the extent buffer bitmap operations and free space tree (patches 2 and 6) - Added Josef's Reviewed-by tags Omar Sandoval (9): Btrfs: add extent buffer bitmap operations Btrfs: add extent buffer bitmap sanity tests Btrfs: add helpers for read-only compat bits Btrfs: refactor caching_thread() Btrfs: introduce the free space B-tree on-disk format Btrfs: implement the free space B-tree Btrfs: add free space tree sanity tests Btrfs: wire up the free space tree to the extent tree Btrfs: add free space tree mount option fs/btrfs/Makefile | 5 +- fs/btrfs/ctree.h | 107 ++- fs/btrfs/disk-io.c | 26 + fs/btrfs/extent-tree.c | 112 ++- fs/btrfs/extent_io.c | 183 +++- fs/btrfs/extent_io.h | 10 +- fs/btrfs/free-space-tree.c | 1501 ++++++++++++++++++++++++++++++++ fs/btrfs/free-space-tree.h | 71 ++ fs/btrfs/super.c | 24 +- fs/btrfs/tests/btrfs-tests.c | 52 ++ fs/btrfs/tests/btrfs-tests.h | 10 + fs/btrfs/tests/extent-io-tests.c | 138 ++- fs/btrfs/tests/free-space-tests.c | 35 +- fs/btrfs/tests/free-space-tree-tests.c | 570 ++++++++++++ fs/btrfs/tests/qgroup-tests.c | 20 +- include/trace/events/btrfs.h | 3 +- 16 files changed, 2763 insertions(+), 104 deletions(-) create mode 100644 fs/btrfs/free-space-tree.c create mode 100644 fs/btrfs/free-space-tree.h create mode 100644 fs/btrfs/tests/free-space-tree-tests.c -- 2.5.1 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
