From 83f92318fa33cc084e14e64dc903e605f75884c1 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Mon, 5 Apr 2010 18:17:16 -0700 Subject: ocfs2: Add dir_resv_level mount option The default behavior for directory reservations stays the same, but we add a mount option so people can tweak the size of directory reservations according to their workloads.
