This is the first pass at making extent-tree.c much smaller. I've purposefully done no other cleanups or changes. The places where I needed to modify callers were done in separate patches. The only time I moved and changed callers in large chunks was the moving of reserve_metadata_bytes out of extent-tree.c, and that was just to rename the users of reserve_metadata_bytes to btrfs_reserve_metadata_bytes. There is 0 functional change in this series. The next step is to move the other space reservation code that is specific to delayed_refs, inodes, etc. But I wanted to start with this to make sure we're all onboard with this approach before I do other things. The diffstat for the whole series is the following fs/btrfs/Makefile | 2 +- fs/btrfs/ctree.h | 97 +--- fs/btrfs/extent-tree.c | 1277 +++---------------------------------------- fs/btrfs/free-space-cache.c | 1 + fs/btrfs/ioctl.c | 1 + fs/btrfs/space-info.c | 1103 +++++++++++++++++++++++++++++++++++++ fs/btrfs/space-info.h | 135 +++++ fs/btrfs/super.c | 1 + fs/btrfs/sysfs.c | 1 + fs/btrfs/volumes.c | 1 + 10 files changed, 1343 insertions(+), 1276 deletions(-) Thanks, Josef
