src/sys/uvm [netbsd-2-0]: uvm_anon.h
Pull up revision 1.17 (requested by yamt in ticket #271):
fix a amap_wirerange deadlock problem by re-introducing
PG_RELEASED for anon pages. PR/23171 from Christian Limpach.
for details, see discussion filed in the PR database.
uvm_anon_release: a new function to free anon-owned PG_RELEASED page.
uvm_anfree: we can't wait for the page here because the caller might hold
amap lock. instead, just mark the page as PG_RELEASED.
who unbusy the page should check the PG_RELEASED.
uvm_aio_aiodone: uvm_anon_release() instead of uvm_page_unbusy()
uvmfault_anonget: check PG_RELEASED.
