1997-04-17Removal of race conditions. Inspired by Charles Hannum'sNiklas Hallqvist
<mycroft@netbsd.org> reorganization of the vm_collapse logic, although not used verbatim. We no longer collapse objects from the pagedaemon as that is not necessary anymore with the more aggressive collapses that gets done. This also increases performance of loaded systems. Much KNF too.
1997-04-10always skip the first 8K of swap. Yes, 8K, not some manufactured number that ↵Theo de Raadt
ends up being 4K
1997-03-29Do not include mmap'ed device memory in coredumps; from Matthias DrochnerThorsten Lockert

1997-03-26Just some initial KNF in preparation for some other changes coming soonNiklas Hallqvist

the object's shadow linkage. Also note that the object is going to die so that a possible collapse can finish early.

1996-08-19A front pager can be lost during pagein, check for this caseNiklas Hallqvist
1996-08-18Restructured vm_object_collapse_aux so sharing object's pageins can go onNiklas Hallqvist
simultaneously without interfering. Also maintain PG_BUSY at pagein time. Removed some statics so gdb will be happier.
1996-08-14IMPORTANT FIX: arbitrary page could be removed during collapse.Niklas Hallqvist
Sanitize "fake" page handling once more.
1996-08-13Clean up vm_object_collapse_aux's dirty page game. Pun intended :-)Niklas Hallqvist

1996-08-12Another VITAL VM patch. Boundary condition not solid, which last commitNiklas Hallqvist
triggered.
1996-08-12Fixed CRITICAL bug hitting in former swap leak scenariosNiklas Hallqvist
when collapsing two objects a formerly COWed page might lose it's backing store causing stuff like lost ld.so fixups of shared lib images. Also handle fake pages in all cases. In short: UPDATE!

1995-12-14from netbsd:Theo de Raadt
Extend use of vm_object_prefer() to vm_allocate_with_pager(). Make vm_object_prefer() call MD aligner for "pageless" objects too, so we can have more control over the virtual address to be used. Implementation could be simpler if we by-pass the object to mapped, but we'd loose the ability to adapt alignment to objects that were previously mmap'ed with MAP_FIXED on. Only expect vm_fork() to return if __FORK_BRAINDAMAGE is defined. Eliminate unused third arg to vm_fork().
