| |
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.
