Subject: [PATCH v2 10/12] udf: Switch udf_adinicb_readpage() to kmap_local_page()
Date: Wed, 25 Jan 2023 10:41:52 +0100 [thread overview]
Message-ID: <20230125094159.10877-10-jack@suse.cz> (raw)
In-Reply-To: <20230125093914.24627-1-jack@suse.cz>
Instead of using kmap_atomic() use kmap_local_page() in
udf_adinicb_readpage().
