:This may seem to be a ridiculous question... (sorry)
:
:I have a question specifically regarding sys/vm/swap_pager.c,
:I'm not very familiar with sys/vm/*, but I've noticed that the value of
:the static int no_swap_space (which is initially set to 1) is almost never
:checked. The only times that this value appears to be changed is during
:checks of vm_swap_size in swap_pager_putpages and swap_pager_copy.
:
:Is this value actually ever checked to determine anything? What exactly is
:its purpose?
:
:Thanks,
:Bosko.
Under -STABLE no_swap_space appears to handle the startup case where
swap has not yet been initialized. It prevents paging to swap from
occuring until the swap system is both initialized and assigned at
least one swap partition.
Under -CURRENT this variable does not exist. The vm/swap_pager.c
in STABLE has been depreciated - that is, it has been completely
rewritten in CURRENT.
