Sage mentioned I was missing a patch. So I''ve retested and updated the git tree. Since Linus did pull my tree yesterday, here''s a new pull request with the single commit. Linus I have this in two flavors. One is merged on top of my for-linus branch, which was 3.1-rc6 + my last pull request: head: 0a7a0519d1789f3a222849421dbe91b6bddb88f5 git://github.com/chrismason/linux.git for-linus Second is just against the btrfs-3.0 tree. I have the two branches just so the N-1 world can update to the latest fixes without running the rest of the rc kernel. I know in the git universe these are all the same, but I''m assuming you''ll want to skip my merge commit: head: b6f3409b2197e8fcedb43e6600e37b7cfbe0715b git://github.com/chrismason/linux.git btrfs-3.0 Sage Weil (1) commits (+6/-1): Btrfs: reserve sufficient space for ioctl clone fs/btrfs/ioctl.c | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-)
