I don't remember if I asked before, but did you test on 4.4? The two latest longterm series are 4.9 and 4.4. 4.7 should be abandoned and forgotten by now really, certainly not used daily in production, it's not even listed on kernel.org anymore. Also it's possible the 4.7 branch that you test did not receive all the bugfix backports from mainline like the longterm series do. > I have no idea what change between 4.7 and 4.9 is responsible for this, but > it's good. FWIW, this appears to be the big Btrfs change between 4.7 and 4.9 (in 4.8): Btrfs: introduce ticketed enospc infrastructure https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=957780eb2788d8c218d539e19a85653f51a96dc1 -- With respect, Roman -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
