PATCH 2.5.72 2/2] i_size atomic access

From: Daniel McNeil (
Date: Thu Jun 19 2003 - 13:17:00 EST

This adds i_seqcnt to the inode structure and then uses i_size_read()
and i_size_write() to provide atomic access to i_size. This is a port
of Andrea Arcangeli's i_size atomic access patch from 2.4. This only
uses the generic reader/writer consistent mechanism.

re-diff against 2.5.72.

This patch has been tested on 1 proc, 2 proc, 4 proc and 8 proc
