Subject: [PATCH 1/6] ipc: Move mqueue fs magic to uapi magic header
Date: Wed, 22 Jul 2026 13:29:37 +0100	[thread overview]
Message-ID: <20260722122952.42149-2-oxana@cloudflare.com> (raw)
In-Reply-To: <20260722122952.42149-1-oxana@cloudflare.com>

Move MQUEUE_MAGIC from ipc/mqueue.c to include/uapi/linux/magic.h so
it can be shared by code outside of ipc/mqueue.c without duplicating
the constant.
