Modified files:
sys/vm vm_map.c vm_map.h vm_pageout.c
Log:
- When the VM daemon is out of swap space and looking for a
process to kill, don't block on a map lock while holding the
process lock. Instead, skip processes whose map locks are held
and find something else to kill.
- Add vm_map_trylock_read() to support the above.
