If you removed this line, then:

We should remove this dput as well, otherwise we will be short of
required reference count on dentry by 1?
Basically, when user does:
# cd /dev/container
# mkdir a
and mkdir returns, what should be the (min) ref count of a's dentry? From my
understanding it should be total number of files under a + 1. The dput
above will cause this reqd count to be short by 1 ..
