[PATCH] drivers/block/loop.c: don't return garbage if LOOP_SET_STATUS not called
While writing a version of losetup, I ran into the problem that the loop
device was returning total garbage.
It turns out the problem was that this losetup was only issuing the
LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl. This
losetup didn't have any special status to set, so it left out the call.
The deeper cause is that loop_set_fd sets the transfer function to NULL,
which causes no transfer to happen lo_do_transfer.
This patch fixes the problem by setting transfer to transfer_none in
loop_set_fd.
