kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x1f/0x30 This was partially set by c2e39305299f01 ("btrfs: clear extent buffer uptodate after we are unsuccessful to write it"), having said that all that resolve did was keep us from discovering extent buffers following a failed writeout. It didn't preserve us from continuing to make use of a buffer that we now experienced found. In this case we're exploring the commit root to cache the block group, so we will start committing the transaction and swap the dedicate root and then get started crafting. once the switch we can easily search for an extent buffer that hasn't been prepared still and start processing that block team. Then we fail to write that block out and clear Uptodate on the site, after which you can we start off spewing these glitches. Generally we're protected because of the tree lock to a certain diploma listed here. If we read a block Now we have that block read through locked, and we block The author from locking the block right before we submit it for that create. having said that this is not always idiot evidence because the examine could come about right before we do the submit_bio and right after we locked and unlocked the extent buffer. Also With this particular case We've route->skip_locking set, so that will not conserve us in this article. we are going to merely have a block which was legitimate when we browse it, but became invalid while we were being here making use of it. What we really need will be to capture the situation the place we've "read through" a block but it is not marked Uptodate. On read we ClearPageError(), so if we're !Uptodate and !mistake we know we didn't do the best point for reading the web site. take care of this by checking !Uptodate && !Error, in this way we is not going to complain if our buffer will get invalidated while we're making use of it, and we will manage the spirit in the check which happens to be to make certain We've got a completely in-cache block when we are messing with it.
