From f232109773ff5b0c840a6761d74940b9cf0d66ec Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 10 Jan 2011 12:12:36 -0500 Subject: ext4: replace i_delalloc_reserved_flag with EXT4_STATE_DELALLOC_RESERVED Remove the short element i_delalloc_reserved_flag from the ext4_inode_info structure and replace it a new bit in i_state_flags. Since we have an ext4_inode_info for every ext4 inode cached in the inode cache, any savings we can produce here is a very good thing from a memory utilization perspective.
