Subject: [PATCH] vmalloc: remove confusing comment on vwrite()
Date: Wed, 9 Mar 2011 15:34:36 +0900 [thread overview]
Message-ID: <1299652476-5185-1-git-send-email-namhyung@gmail.com> (raw)
KM_USER1 is never used for vwrite() path so the caller
doesn't need to guarantee it is not used. Only the caller
should guarantee is KM_USER0 and it is commented already.
