Subject: [RFC] [patch 0/3] i_version update for ext4
Date: Tue, 23 Jan 2007 18:23:54 +0100 [thread overview]
Message-ID: <45B644AA.1070409@bull.net> (raw)
Hello,
I've updated what was previously the change attribute patch for ext4
initially posted by Alexandre Ratchov. The previous patch was
introducing a change_attribute field, now it uses the i_version field of
the inode.
The i_version field is a counter that is set on every inode creation and
that is incremented every time the inode data is modified (similarly to
the "ctime" time-stamp).
The aim is to fulfill NFSv4 requirements for rfc3530.
For the moent, the counter is only a 32bit value but it is planned to be
64bit as required.
The patch is divided into 3 parts, the vfs layer, the ext4 specific code
and an user part to check i_version changes via stat.
Any comments are welcome.
regards,
Jean noel
