sys/vm default_pager.c swap_pager.c swap_pager.h
vm_kern.c vm_map.c vm_object.c
vm_pageout.c vm_swap.c vm_zone.c
Log:
- If swap metadata does not fit into the KVM, reduce the number of
struct swblock entries by dividing the number of the entries by 2
until the swap metadata fits.
- Reject swapon(2) upon failure of swap_zone allocation.
This is just a temporary fix. Better solutions include:
(suggested by: dillon)
o reserving swap in SWAP_META_PAGES chunks, and
o swapping the swblock structures themselves.
