From 35d8c7ad7208dad5d352c483408e555022750978 Mon Sep 17 00:00:00 2001 From: Hillf Danton Date: Mon, 31 Oct 2011 17:09:40 -0700 Subject: [PATCH] mm/huge_memory: fix typo when updating mmu cache There are three cases of update_mmu_cache() in the file, and the case in function collapse_huge_page() has a typo, namely the last parameter used, which is corrected based on the other two cases. Due to the define of update_mmu_cache by X86, the only arch that implements THP currently, the change here has no really crystal point, but one or two minutes of efforts could be saved for those archs that are likely to support THP in future.
