This is necessary since malloc 1996-06-15T12:29:19Z David Greenman dg@FreeBSD.org 1996-06-15T12:29:19Z urn:sha1:3901d8e3f2f2437d323fa5637f03a0f80f0d37a8 can/will allocate map entries at interrupt time. This is similar to a (splvm) change that was made in the main branch, but much simpler. The code in the main branch is broken (the thresholds are of such that freed map entries will accumulate on the non-kernel pool)...so the fix was re-implemented with just the spl protection and minor algorithmic simplification. Fixes for a couple of minor bugs: 1996-04-26T04:12:18Z David Greenman dg@FreeBSD.org 1996-04-26T04:12:18Z urn:sha1:fa70835c8d5dfb15c205eb6c4a3fbce6a132614d 1) allocate map VM from the kernel_map, not the kmem_map. 2) update map hint properly when simplifying a map and remove unnecessary restriction on object->paging_in_progress. The above problems wouldn't have caused any panics, and it's unlikely that there were any noticeable effects due to the bugs...but they're bugs nonetheless. Submitted by: dyson Brought in change from rev 1.26: moved vm_map_lock call to close window. 1995-11-12T08:59:56Z David Greenman dg@FreeBSD.org 1995-11-12T08:59:56Z urn:sha1:6022327014046f6f42a6622bb1f10406fb8a8d2b Remove trailing whitespace. 1995-05-30T08:16:23Z Rodney W.

Removed some completely unused globals. Pass syncio flag to vm_object_clean(). It remains unimplemented, however. 1995-03-25T17:36:57Z David Greenman dg@FreeBSD.org 1995-03-25T17:36:57Z urn:sha1:492d73bd99ccf5b20f1419e5a58bad0116731bbd Removed unused fifth argument to vm_object_page_clean().

Added check to make sure that vm_object_remove() isn't called with a NULL pager or for a pager for an OBJ_INTERNAL object (neither of which will be on the hash list). Clear OBJ_CANPERSIST if we decide to terminate it because of no resident pages.
