Linux

Hi,

initially i will mount a image using loop device using below command

Code:

mount -n -o loop,noatime,ro -t squashfs /mnt/fsh/bt.img /opt/app/test

then "mount" reflects with below

Code:

/dev/loop0 on /opt/app/test type squashfs (ro,noatime)

i will then umount using below commnd, umount is successfull

Code:

umount /opt/app/test

After this "mount" output does not have loop0, but "losetup" still shows

Code:

/dev/loop0: 0 /mnt/fsh/bt.img

How do i umount such that losetup will be free loop device for bt.img ??
