But that's just the happy path. Along the way previous\nallocations might have gone wrong, or we might not get -EIOCBQUEUED from\nbtrfs_encoded_read_regular_fill_pages(). In all these cases, we go to a\ncleanup section that frees all memory allocated by this function without\nassuming any deferred execution, and this also needs to happen for the\n'pages' allocation."
