If anyone has any objections, please let me know. ------------------ From: Baokun Li commit 369c944ed1d7c3fb7b35f24e4735761153afe7b3 upstream. Even though ext4_find_extent() returns an error, ext4_insert_range() still returns 0. This may confuse the user as to why fallocate returns success, but the contents of the file are not as expected. So propagate the error returned by ext4_find_extent() to avoid inconsistencies.
