Subject: [patch] hugetlb: allow sticky directory mount option
Date: Sat, 20 Oct 2007 11:08:58 -0700 [thread overview]
Message-ID: <b040c32a0710201108r70822a8m5fc1286f17083605@mail.gmail.com> (raw)
Allow sticky directory mount option for hugetlbfs. This allows admin
to create a shared hugetlbfs mount point for multiple users, while
prevent accidental file deletion that users may step on each other.
It is similiar to default tmpfs mount option, or typical option used
on /tmp.
