I had just sent two patches to fix false enospc error for compression,
please have a try, they fix false enospc error in my test environment.
         btrfs: fix false enospc for compression
         btrfs: improve inode's outstanding_extents computation

I apply these two patchs in linux upstream tree, the latest commit
is 41844e36206be90cd4d962ea49b0abc3612a99d0.

Xiaoguang Wang
