Subject: [PATCH 39/39] KVM: rename is_writeble_pte() to is_writable_pte()
Date: Sat, 13 Feb 2010 10:01:59 +0200	[thread overview]
Message-ID: <1266048119-14325-40-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1266048119-14325-1-git-send-email-avi@redhat.com>

From: Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp>

There are two spellings of "writable" in
arch/x86/kvm/mmu.c and paging_tmpl.h .

This patch renames is_writeble_pte() to is_writable_pte()
and makes grepping easy.

  New name is consistent with the definition of itself:
  return pte & PT_WRITABLE_MASK;
