alc 2010-04-28 04:57:32 UTC FreeBSD src repository Modified files: sys/vm vm_object.c Log: SVN rev 207306 on 2010-04-28 04:57:32Z by alc Change vm_object_madvise() so that it checks whether the page is invalid or unmanaged before acquiring the page queues lock. Neither of these tests require that lock. Moreover, a better way of testing if the page is unmanaged is to test the type of vm object. This avoids a pointless vm_page_lookup(). MFC after: 3 weeks Revision Changes Path 1.413 +6 -10 src/sys/vm/vm_object.c
