However, now that other threads can be allocating pages while the inactive queue scan is running, it's an unreliable method. The effect of it being unreliable is that we can start swapping out processes when we didn't intend to. This issue has existed since the kernel was multithreaded, but the changes to the inactive queue target in 10.0-RELEASE have made its effects visible. This change introduces a more direct method for determining if the inactive queue scan met its target that is not affected by the actions of other threads. 2014-09-01T07:58:15Z Konstantin Belousov kib@FreeBSD.org 2014-09-01T07:58:15Z urn:sha1:7676b49b19cd991f895fe69fa0dda713a65f514d wired region. Rework the handling of unwire to do the it in batch, both at pmap and object level. All commits below are by alc. MFC r268327: Introduce pmap_unwire(). MFC r268591: Implement pmap_unwire() for powerpc. MFC r268776: Implement pmap_unwire() for arm. MFC r268806: pmap_unwire(9) man page. MFC r269134: When unwiring a region of an address space, do not assume that the underlying physical pages are mapped by the pmap. This fixes a leak of the wired pages on the unwiring of the region mapped with no access allowed. MFC r269339: In the implementation of the new function pmap_unwire(), the call to MOEA64_PVO_TO_PTE() must be performed before any changes are made to the PVO. Otherwise, MOEA64_PVO_TO_PTE() will panic. MFC r269365: Correct a long-standing problem in moea{,64}_pvo_enter() that was revealed by the combination of r268591 and r269134: When we attempt to add the wired attribute to an existing mapping, moea{,64}_pvo_enter() do nothing. (They only set the wired attribute on newly created mappings.) MFC r269433: Handle wiring failures in vm_map_wire() with the new functions pmap_unwire() and vm_object_unwire(). Retire vm_fault_{un,}wire(), since they are no longer used. MFC r269438: Rewrite a loop in vm_map_wire() so that gcc doesn't think that the variable "rv" is uninitialized. MFC r269485: Retire pmap_change_wiring().
