btrfs receive deadlock and questions

2019-01-22 Thread Eli V
I seem to have it a deadlock trying out btrfs send & receive. Now I haven't used btrfs send & receive much, so don't have much experience with them. Anyways, bug report and stack traces: https://bugzilla.kernel.org/show_bug.cgi?id=202383 Seems like the receive is hung as well as several kworkers.

I've seen similar symptoms running rsync(https://bugzilla.kernel.org/show_bug.cgi?id=199753), and the hangs always seem to have the wait_woken() in the stack trace. Doesn't happen repeatably for me, though I ran 4.18.6 for a month without issues, and had freezes the first(and only) two times I ran
