kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x1f/0x30 This was partly set by c2e39305299f01 ("btrfs: crystal clear extent buffer uptodate whenever we fail to write it"), having said that everything correct did was retain us from locating extent buffers following a failed writeout. It did not continue to keep us from continuing to make use of a buffer that we now experienced identified. In such cases we're seeking the commit root to cache the block team, so we could commence committing the transaction and swap the commit root and then start producing. following the swap we are able to lookup an extent buffer that has not been composed but and begin processing that block group. Then we fall short to jot down that block out and distinct Uptodate about the site, and then we start off spewing these glitches. Normally we are shielded because of the tree lock to a certain diploma below. If we read a block We have now that block go through locked, and we block The author from locking the block ahead of we post it for the compose. However this isn't necessarily idiot evidence since the go through could come about before we do the submit_bio and soon after we locked and unlocked the extent buffer. Also in this distinct case We have now route->skip_locking established, so that will not preserve us below. We'll just obtain a block that was legitimate after we read it, but grew to become invalid even though we were utilizing it. What we actually need is always to catch the situation where by we've "go through" a block but it isn't really marked Uptodate.
