Ok. > What happens when you create a loop device on a write-sealed descriptor? Any write-back to the loop-device will fail with EPERM as soon as the fd gets write-sealed. See __do_lo_send_write() in drivers/block/loop.c. It's up to the loop-device to forward the error via bio_endio() to the caller for proper error-handling.
