Hi everyone, I've got a nice set of fixes from Josef, Jan, Ilya and others in my for-linus branch: git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus Some of the changes are fixes for the tree logging code, so I ran some extra crash runs against them Friday night. I ended up with a new crash in the tree log directory deletion replay code, so I didn't send out the pull request to Linus. It isn't clear yet if the new crash is because I was testing differently or if it is a regression. I'm nailing it down this weekend, but please give my for-linus a shot.I consistently run into this assertion [1] while running a fio workload on a fresh RAID10 filesystem with a balance running. Let me know if you need steps to reproduce, debug etc.
Seems that additional condition does not catch the bug. Plz show us the steps to reproduce, I'll try to reproduce it locally and nail it down. thanks, liubo
