From 8809aa2d28d74111ff2f1928edaa4e9845c97a7d Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Wed, 24 Jun 2015 16:57:44 -0700 Subject: mm: clarify that the function operates on hugepage pte We have confusing functions to clear pmd, pmd_clear_* and pmd_clear. Add _huge_ to pmdp_clear functions so that we are clear that they operate on hugepage pte. We don't bother about other functions like pmdp_set_wrprotect, pmdp_clear_flush_young, because they operate on PTE bits and hence indicate they are operating on hugepage ptes Signed-off-by: Aneesh Kumar K.V Acked-by: Kirill A.
