Subject: [PATCH io_uring for-6.18 17/20] io_uring/zcrx: don't adjust free cache space
Date: Tue, 16 Sep 2025 15:28:00 +0100 [thread overview]
Message-ID: <c8e94ec4b524bb2efb91b8ae2636d830d6b56f0c.1758030357.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1758030357.git.asml.silence@gmail.com>
The cache should be empty when io_pp_zc_alloc_netmems() is called,
that's promised by page pool and further checked, so there is no need to
recalculate the available space in io_zcrx_ring_refill().
