Modified: sys/kern init_main.c
sys/vm vm_glue.c vm_pageout.c
Log:
Retrofitted changes to add NO_SWAPPING option from -current (actually, it's
the other way around - the changes in -current were based on these).
The NO_SWAPPING option disables U-area paging (struct user & kernel stack)
and can help improve performance in some special circumstances where a
system has plenty of main memory and also has a lot of processes that are
often in short waits (< 1 minute) but wake up frequently. Such is the
case on a busy FTP archive like wcarchive. This option does not affect
generic VM system paging.
