Looking at the code, it seems that vm_page_unwire() only requires the page to be locked if it is managed. As it was acquired by contigmalloc, the page should be unmanaged so that should be ok. I am confused as to why vm_page_unwire() does not require the page to be locked if the page is unmanaged. What is synchronizing the accesses to m->wire_count?Received on Wed May 26 2010 - 17:56:10 UTC
