From f91a0d3e24e4b0198be5fae20d45a35c40d1efce Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 15 Oct 2007 16:29:05 +0100 Subject: [GFS2] Remove useless i_cache from inodes The i_cache was designed to keep references to the indirect blocks used during block mapping so that they didn't have to be looked up continually. The idea failed because there are too many places where the i_cache needs to be freed, and this has in the past been the cause of many bugs. In addition there was no performance benefit being gained since the disk blocks in question were cached anyway. So this patch removes it in order to simplify the code to prepare for other changes which would otherwise have had to add further support for this feature.
