| H A D | tmpfs_vnops.c | diff 207530 Sun May 02 15:44:00 MDT 2010 alc It makes no sense for vm_page_sleep_if_busy()'s helper, vm_page_sleep(), to unconditionally set PG_REFERENCED on a page before sleeping. In many cases, it's perfectly ok for the page to disappear, i.e., be reclaimed by the page daemon, before the caller to vm_page_sleep() is reawakened. Instead, we now explicitly set PG_REFERENCED in those cases where having the page persist until the caller is awakened is clearly desirable. Note, however, that setting PG_REFERENCED on the page is still only a hint, and not a guarantee that the page should persist. |
