Subject: [PATCH 05/20] udf: Move udf_expand_dir_adinicb() to its callsite
Date: Fri, 16 Dec 2022 16:24:09 +0100	[thread overview]
Message-ID: <20221216152656.6236-5-jack@suse.cz> (raw)
In-Reply-To: <20221216121344.14025-1-jack@suse.cz>

There is just one caller of udf_expand_dir_adinicb(). Move the function
to its caller into namei.c as it is more about directory handling than
anything else anyway.
