Robbie Ko bf93dda2fd btrfs: fix page leaks after failure to lock page for delalloc ... commit 5909ca110b29aa16b23b52b8de8d3bb1035fd738 upstream. When locking pages for delalloc, we check if it's dirty and mapping still matches. If it does not match, we need to return -EAGAIN and release all pages. Only the current page was put though, iterate over all the remaining pages too.
