Hi all, Having cleaned up the rtbitmap code and fixed various weird bugs in the allocator, now we want to do some more cleanups to the rt free space management code to get it ready for the introduction of allocation groups. 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=rtgroups-prep xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=rtgroups-prep --- Commits in this patchset: * iomap: add a merge boundary flag --- fs/iomap/buffered-io.c | 6 ++++++ include/linux/iomap.h | 4 ++++ 2 files changed, 10 insertions(+)
