Hi, > From: Filipe Manana <fdmanana@xxxxxxxx> > > commit 939b656bc8ab203fdbde26ccac22bcb7f0985be5 upstream. > > During an append (O_APPEND write flag) direct IO write if the input buffer > was not previously faulted in, we can corrupt the file in a way that the > final size is unexpected and it includes an unexpected hole. Could we apply the patch 70f1e5b6db56ae99ede369d25d5996fa50d7bb74 btrfs: rename err to ret in btrfs_direct_write() to 6.6 stable, and then rebase this patch?
