• Next Patch: AIC7xxx SCSI Driver for Linux 2.1.36
  

This extends the /proc/stat function to give you a little insight into the cache statistics of the directory name, general buffer cache, and the FAT cache.

It'll look like this now:

cpu  664111 196 4537 417250
disk 29967 6 1 1
disk_rio 26491 3 1 1
disk_wio 3476 3 0 0
disk_rblk 58169 18 2 2
disk_wblk 27808 24 0 0
page 27723 4642
swap 3 4
intr 1335631 1086094 15054 0 0 197142 0 3 0 8 0 0 0 7257 1 29993 79
ctxt 100713
btime 862687154
processes 336
dircache 335650 8398
bufcache 629995 80585
fatcache 2950 1330

First number is the hit, 2nd number is the miss.
