From 85d1da67f7e1239afa3494d05be87da6fc3ecada Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 7 Sep 2006 14:40:21 -0400 Subject: [GFS2] Move glock hash table out of superblock There are several reasons why we want to do this: - Firstly its large and thus we'll scale better with multiple GFS2 fs mounted at the same time - Secondly its easier to scale its size as required (thats a plan for later patches) - Thirdly, we can use kzalloc rather than vmalloc when allocating the superblock (its now only 4888 bytes) - Fourth its all part of my plan to eventually be able to use RCU with the glock hash.
