Hello,
does anyone know off the top of their head which piece
of code writes the "disk_io:" entry in /proc/stat ?
I've been trying to make some sense of this entry without
much success and have so far been unsuccessful at locating
the source.
TIA

drive_stat_acct() in drivers/block/ll_rw_blk.c gathers the data,
kstat_read_proc() in fs/proc/proc_misc.c implements the output routine.
Format is (device major, disk index):(sum of all io requests,
sum of read io requests, sum of blocks read, sum of write io requests,
sum of blocks written)
Daniel.
