I found that compress sometime report ENOSPC error even in 4.8-rc8,

I might not get you, my poor english :)
You mean that you only get ENOSPC error when compression is enabled?
And when compression is not enabled, you do not get ENOSPC error?
I can't tell you. I cannot test with compression not enabled. I do not
have anough free space on this disk.
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.
no space errors since 5 days! that's currently amazing. I Hope it stays
this and your patches get into 4.9.
Yeah, good news :)
OK, I'll try to get these 2 patches merged, currently they still need
some code reviews from maintainers.

I'm trying to fix it.
That sounds good but do you also get the
BTRFS: space_info 4 has 18446742286429913088 free, is not full
kernel messages on umount? if not you might have found another problem.
Yes, I seem similar messages, you can paste you whole dmesg info here.
