Btrfs: don't do anything in our ->freeze_fs and ->unfreeze_fs (926ced12) · Commits · 戴 / test

We do not need to do anything special to freeze or unfreeze, it's all taken care of by the generic work, and what we currently have is wrong anyway since we shouldn't be returnning to userspace with mutexes held anyway. Thanks, Signed-off-by:
