hung tasks on resume
Hi!
I had another BTRFS hang¹. It may be related to the kworker at 100% on write issue that still happened with 4.0 kernels² as / device was 100% allocated and it seems that bug doesn´t happen if there is still device space left to be allocated for chunks.
But this time it was on resume from hibernation. All I could get was a backtrace on the console.
IMHO this still is not production ready, despite any other sayings.
