Subject: Re: [PATCH 0/2] overlayf
nt/restore functionality
of overlayfs mounts in case when we have overmounts on
lowerdir, workdir, upperdir paths.

fs
from dcache.c is used to resolve full path
in mount namespace. This function also adds "(deleted)" suffix
if dentry was deleted. So, If one of dentries in lowerdir, upperdir,
workdir options is deleted, we will see "(deleted)" suffix in
corresponding path.
