From 88b6edd17c62b7d346d21f4087893ce7d4ef828a Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 25 May 2009 11:50:39 -0400 Subject: ext4: Clean up calls to ext4_get_group_desc() If the caller isn't planning on modifying the block group descriptors, there's no need to pass in a pointer to a struct buffer_head. Nuking this saves a tiny amount of CPU time and stack space usage.
