From b90c062c65cc8839edfac39778a37a55ca9bda36 Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Tue, 28 Jul 2009 15:26:59 -0300 Subject: KVM: MMU: fix bogus alloc_mmu_pages assignment Remove the bogus n_free_mmu_pages assignment from alloc_mmu_pages. It breaks accounting of mmu pages, since n_free_mmu_pages is modified but the real number of pages remains the same.
