alc b57e5e03fd Make vm_page's PG_ZERO flag immutable between the time of the page's ... allocation and deallocation. This flag's principal use is shortly after allocation. For such cases, clearing the flag is pointless. The only unusual use of PG_ZERO is in vfs_bio_clrbuf(). However, allocbuf() never requests a prezeroed page. So, vfs_bio_clrbuf() never sees a prezeroed page. Reviewed by: tegge@		2004-05-06 05:03:23 +00:00
