Hello,I add libhugetlbfs package into my rootfs and run the below command in my board . root@p1021rdb:~# hugeadm --create-mounts hugeadm:WARNING: Unable to add entry /var/lib/hugetlbfs/pagesize-4MB to /etc/mtab, error: Invalid argument hugeadm:WARNING: Unable to add entry /var/lib/hugetlbfs/pagesize-16MB to /etc/mtab, error: Invalid argument
This looks like the hugeadm may be broken in some way. The writing to the mounts and behavior should be based on the way the standard mount does it.
If the hugeadm uses standard mount resources, then the entries it adds should have showed up into the /proc/mounts automatically.
