[PATCH 2.5.67 2/2] i_size atomic access

From: Daniel McNeil (daniel@osdl.org)
Date: Fri Apr 18 2003 - 13:55:32 EST


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

re-diff against 2.5.67.

This patch is available for download from OSDL's patch lifecycle
manageer (PLM):

http://osdl.org/cgi-bin/plm?module=patch_info&patch_id=1779

This has been tested on a 2-proc system and using OSDL's STP
(http://www.osdl.org/stp/).

Andrew, can we get this into -mm?

Thanks,
