Subject: Re: [PATCH -V14 0/11] Generic name to handle and open by handle syscalls
Date: Wed, 7 Jul 2010 21:39:21 +0100	[thread overview]
Message-ID: <20100707213921.2edbb3a1@lxorguk.ukuu.org.uk> (raw)
In-Reply-To: <5920F408-E923-4467-A6A9-6C0923C00927@oracle.com>

> I think you are assuming too much about the use of the file handle.  What I'm interested in is not a userspace file server, but rather a more efficient way to have 10000's to millions of clients to be able to open the same regular file, without having to do full path traversal for each one.

The unix security model requires the traversal. In that respect it
differs significantly from some other OS's that did have handle based
direct opens and treat directories as a lookup and translation index only.
