Thomas Lavocat da11ef4eb0 loop: use LOOP_CONFIGURE instead of LOOP_SET_FD ... LOOP_CONFIGURE allows to atomically configure the decive when opening it. This avoid the possibility of a race condition where between set_fd and set_status some operations are already accepted by the loopback device. See https://lwn.net/Articles/820408/ This feature was included in the linux kernel 5.8 however it is safe to not include any kind of fallback to the previous method as @obudai points out that: LOOP_CONFIGURE was backported into RHEL 8 kernel in RHEL 8.4 as a part of https://bugzilla.redhat.com/show_bug.cgi?id=1881760 (block layer: update to upstream v5.8). Since RHEL 8.4 is currently the oldest supported release that we support running osbuild on, it might be just fine implementing this without the fallback.
