The umount command will also free that loopback + device. + + You can still use the 'losetup' utility (to manually associate files + with loop devices) if you need to do something advanced, such as + specify an offset or cryptographic options to the loopback device. + (If you don't want umount to free the loop device, use "umount -D".) + +config FEATURE_MOUNT_LOOP_CREATE + bool "Create new loopback devices if needed" + default n + depends on FEATURE_MOUNT_LOOP + help + Linux kernels >= 2.6.24 support unlimited loopback devices.
