Subject: [PATCH 1/8] mm: Rename PF argument to modify
Date: Fri, 13 Apr 2018 21:31:38 -0700 [thread overview]
Message-ID: <20180414043145.3953-2-willy@infradead.org> (raw)
In-Reply-To: <20180414043145.3953-1-willy@infradead.org>
From: Matthew Wilcox <mawilcox@microsoft.com>
I find the word 'enforce' misleading; this flag is set for Set and Clear
and clear for Test, so the word 'modify' seems more descriptive than
'enforce'.
