Modified Files:
src/sys/kern: vfs_bio.c
Log Message:
If we're only doing a count-only kern.buf sysctl, just return the number
of active members in the pool cache (plus some slop) instead of looking
in all the free buffer list. Should reduce CPU usage for "systat vm"
to << 1% especially for machines with a larger number of buffers.
