Subject: [PATCH 1/2] inboxwritable: delay umask_prepare calls
Date: Thu, 24 Dec 2020 10:09:18 +0000
Message-ID: <20201224100919.30927-2-e@80x24.org> (raw)
In-Reply-To: <20201224100919.30927-1-e@80x24.org>

This simplifies all ->with_umask callers and opens the
door for further optimizations to delay/elide process spawning.
