Subject: [PATCH 4.19 09/72] 9p: embed fcall in req to round down buffer allocs
Date: Tue,  2 Jul 2019 10:01:10 +0200	[thread overview]
Message-ID: <20190702080125.059583519@linuxfoundation.org> (raw)
In-Reply-To: <20190702080124.564652899@linuxfoundation.org>

[ Upstream commit 523adb6cc10b48655c0abe556505240741425b49 ]

'msize' is often a power of two, or at least page-aligned, so avoiding
an overhead of two dozen bytes for each allocation will help the
allocator do its work and reduce memory fragmentation.
