Subject: [PATCH 1/2] cfi: Flip headers
Date: Mon, 20 Nov 2023 15:46:43 +0100 [thread overview]
Message-ID: <20231120154948.598460288@infradead.org> (raw)
In-Reply-To: 20231120144642.591358648@infradead.org
Normal include order is that linux/foo.h should include asm/foo.h, CFI has it
the wrong way around.
