    Btrfs: prepare block group cache before writing · dcdf7f6d
    Josef Bacik authored
    Writing the block group cache will modify the extent tree quite a bit because it
    truncates the old space cache and pre-allocates new stuff.  To try and cut down
    on the churn lets do the setup dance first, then later on hopefully we can avoid
    looping with newly dirtied roots.  Thanks,
