------------------------------------------------------
Subject: ext2 statfs improvement for block and inode free count
From: Badari Pulavarty <[EMAIL PROTECTED]>
More statfs() improvements for ext2. ext2 already maintains percpu
counters for free blocks and inodes. Derive free block count and inode
count by summing up percpu counters, instead of counting up all the groups
in the filesystem each time.
