From 0467ae954d1843de65e7cf8f706f88fe65cd8418 Mon Sep 17 00:00:00 2001 From: Sunil Mushran Date: Wed, 5 May 2010 16:25:08 -0700 Subject: [PATCH] ocfs2/dlm: Increase o2dlm lockres hash size Lockres hash size of 16KB is far too small for large filesystems (where we have hundreds of thousands of lock resources stored in the table). This patch increases it to 128KB.
