Subject: [PATCH] rename is_mlocked_vma() to mlocked_vma_newpage()
Date: Wed, 25 Apr 2012 10:45:55 -0700	[thread overview]
Message-ID: <1335375955-32037-1-git-send-email-yinghan@google.com> (raw)

Andrew pointed out that the is_mlocked_vma() is misnamed. A function
with name like that would expect bool return and no side-effects.

Since it is called on the fault path for new page, rename it in this
patch.
