Matthew Dillon 245df27cee Implement kern.maxvnodes. adjusting kern.maxvnodes now actually has a ... real effect. Optimize vfs_msync(). Avoid having to continually drop and re-obtain mutexes when scanning the vnode list. Improves looping case by 500%. Optimize ffs_sync(). Avoid having to continually drop and re-obtain mutexes when scanning the vnode list. This makes a couple of assumptions, which I believe are ok, in regards to vnode stability when the mount list mutex is held. Improves looping case by 500%. (more optimization work is needed on top of these fixes) MFC after: 1 week		2001-10-26 00:08:05 +00:00
