Steven Whitehouse 17d539f049 GFS2: Cache dir hash table in a contiguous buffer ... This patch adds a cache for the hash table to the directory code in order to help simplify the way in which the hash table is accessed. This is intended to be a first step towards introducing some performance improvements in the directory code. There are two follow ups that I'm hoping to see fairly shortly. One is to simplify the hash table reading code now that we always read the complete hash table, whether we want one entry or all of them. The other is to introduce readahead on the heads of the hash chains which are referred to from the table. The hash table is a maximum of 128k in size, so it is not worth trying to read it in small chunks. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>		2011-07-15 09:31:48 +01:00
