Subject: Re: [PATCH 2/2] vfs: don't allow writes to swap files
Date: Thu, 15 Aug 2019 23:41:21 -0700
Message-ID: <20190816064121.GB2024@infradead.org> (raw)
In-Reply-To: <156588515613.111054.13578448017133006248.stgit@magnolia>

The new checks look fine to me, but where does the inode_drain_writes()
function come from, I can't find that in my tree anywhere.

Also what does inode_drain_writes do about existing shared writable
mapping?  Do we even care about that corner case?
