If anyone has any objections, please let me know. ------------------ From: Jes Sorensen commit 203d27b0226a05202438ddb39ef0ef1acb14a759 upstream. This was introduced with 9e882242c6193ae6f416f2d8d8db0d9126bd996b which changed the return value of submit_bio_wait() to return != 0 on error, but didn't update the caller accordingly.
