From 9900ba3487f9ba392db30e12d210f768a90abb13 Mon Sep 17 00:00:00 2001 From: Mingming Cao Date: Wed, 14 Jan 2009 16:18:57 +0100 Subject: [PATCH] quota: Use inode->i_blkbits to get block bits Andrew has suggested to use inode->i_blkbits to get the block bits info, rather than use super block's blockbits. That should be faster and emit less code.
