[LTP] [PATCH 08/10] Add landlock04 test

[Andrea Cervesato]

Hi Li,

thanks for catching it. I had to install exfat in my VM in order to test it.
Indeed, I think exfat doesn't support char/block/sock devices, since its 
focus is mainly SD cards and USB drives.

We can easily skip that specific FS from the test, as I already done for 
vfat.
