Subject: [PATCH v4 07/11] exfat: fix implicit declaration of brelse()
Date: Mon, 18 May 2026 20:47:01 +0900	[thread overview]
Message-ID: <20260518114705.9601-8-linkinjeon@kernel.org> (raw)
In-Reply-To: <20260518114705.9601-1-linkinjeon@kernel.org>

exfat_cluster_walk() calls brelse(bh) without including the header that
declares the function, causing the following build error:

    fs/exfat/exfat_fs.h:542:9: error: implicit declaration of function ‘brelse’ [-Werror=implicit-function-declaration]

Fix this by adding the missing buffer_head.h in exfat_fs.h.

Acked-by: Christoph Hellwig <hch@lst.de>
