Subject: [PATCH] vmacct5/9 remove unhelpful vm_unacct_vma
Date: Mon, 29 Jul 2002 23:10:24 +0100 (BST) [thread overview]
Message-ID: <Pine.LNX.4.21.0207292309210.1184-100000@localhost.localdomain> (raw)
In-Reply-To: <Pine.LNX.4.21.0207292257001.1184-100000@localhost.localdomain>
Remove vm_unacct_vma function: it's only used in one place,
which can do it better by using vm_unacct_memory directly.
