Subject: [PATCH] md: remove unused static md_wq workqueue
Date: Sat, 28 Mar 2026 20:35:22 +0100 [thread overview]
Message-ID: <20260328193522.3624-1-abd.masalkhi@gmail.com> (raw)
The md_wq workqueue is defined as static and initialized in md_init(),
but it is not used anywhere within md.c.
All asynchronous and deferred work in this file is handled via
md_misc_wq or dedicated md threads.
Fixes: b75197e86e6d3 ("md: Remove flush handling")
