Modified files:
sys/i386/i386 machdep.c
sys/kern vfs_bio.c
sys/sys buf.h
Log:
Adjust the buffer cache to better handle small-memory machines. A
slightly older version of this code was tested by BDE and I.
Also fixes a lockup situation when kva gets too fragmented.
Remove the maxvmiobufspace variable and sysctl, they are no longer
used. Also cleanup (remove) #if 0 sections from prior commits.
This code is more of a hack, but presumably the whole buffer cache
implementation is going to be rewritten in the next year so it's no
big deal.
