Subject: Call uvm_pglistfree(9) instead of uvm_pmr_freepageq().
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=7f144f4ceabe13eb54795db3c1858c4ab25a96d4;p=openbsd

Call uvm_pglistfree(9) instead of uvm_pmr_freepageq().

There is no functionnal change as the former is just a wrapper around the
latter.  However upper layer of UVM do not need to mess with the internals
of the page allocator.

This will also help when a page cache will be introduced to reduce contention
on the global mutex serializing acess to pmemrange's data.
