mount: read /sys for loopdev backing file
On systems without /etc/mtab (or everywhere if kernel >= 2.6.37) we use loop autoclear flag and then the backing file name is not stored in /etc/mtab. mount(8) uses sysfs to get the filename (or LOOP_GET_STATU* ioctls on old kernels). Signed-off-by: Karel Zak <kzak@redhat.com>
