From cde6436004ad9cd8cab5a874b6fa8b01f1da91bf Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Tue, 4 Nov 2008 18:46:03 -0500 Subject: [PATCH] ext4: Remove i_ext_generation from ext4_inode_info structure The i_ext_generation was incremented, but never used. Remove it to slim down the ext4_inode_info structure.
