In inode.c:btrfs_page_exists_in_range(), if the page we got from the radix tree is an exception entry, which can't be retried, we exit the loop with a non-NULL page and then call page_cache_release against it, which is not ok since it's not a valid page. This could also make us return true when we shouldn't. Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com> --- fs/btrfs/inode.c | 1 + 1 file changed, 1 insertion(+)
