SubjectRe: [PATCH] loop.c patches, take two
 static inline void loop_handle_bio(struct loop_device *lo, struct bio *bio)
{
int ret;
+ struct bio *rbh;
- /*
- * For block backed loop, we know this is a READ
- */
if (lo->lo_flags & LO_FLAGS_DO_BMAP) {
ret = do_bio_filebacked(lo, bio);
bio_endio(bio, bio->bi_size, ret);
- } else {
- struct bio *rbh = bio->bi_private;
+ } else if (bio_rw(bio) == WRITE) {
+ /*

AFAICS, this code path is never taken. You don't queue block device writes for the loop thread.


+ * Write complete, but more pages remain;
+ * encrypt and write some more pages
+ */
+ loop_recycle_buffer(lo, bio);
