Alex Tomas 09fe316a7b [PATCH] fast ext3_statfs 
Under I/O load it may take up to a dozen seconds to read all group
descriptors.  This is what ext3_statfs() does.  At the same time, we already
maintain global numbers of free inodes/blocks.  Why don't we use them instead
of group reading and summing?
