From 5786be7cc764b4afb216ff9ca21cab50f69ddcc3 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 9 Aug 2006 17:43:27 +0000 Subject: Introduce a field to struct vm_page for storing flags that are synchronized by the lock on the object containing the page. Transition PG_WANTED and PG_SWAPINPROG to use the new field, eliminating the need for holding the page queues lock when setting or clearing these flags. Rename PG_WANTED and PG_SWAPINPROG to VPO_WANTED and VPO_SWAPINPROG, respectively. Eliminate the assertion that the page queues lock is held in vm_page_io_finish(). Eliminate the acquisition and release of the page queues lock around calls to vm_page_io_finish() in kern_sendfile() and vfs_unbusy_pages(). --- sys/fs/nwfs/nwfs_io.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sys/fs/nwfs') diff --git a/sys/fs/nwfs/nwfs_io.c b/sys/fs/nwfs/nwfs_io.c index b74cd4a4f488..3071fe1f78ae 100644 --- a/sys/fs/nwfs/nwfs_io.c +++ b/sys/fs/nwfs/nwfs_io.c @@ -483,7 +483,7 @@ nwfs_getpages(ap) * now tell them that it is ok to use. */ if (!error) { - if (m->flags & PG_WANTED) + if (m->oflags & VPO_WANTED) vm_page_activate(m); else vm_page_deactivate(m); -- cgit v1.2.3
