Subject: [PATCH 6.1 10/25] udf: Do not bother looking for prealloc extents if i_lenExtents matches i_size
Date: Mon, 19 Dec 2022 20:22:49 +0100 [thread overview]
Message-ID: <20221219182943.825756132@linuxfoundation.org> (raw)
In-Reply-To: <20221219182943.395169070@linuxfoundation.org>
From: Jan Kara <jack@suse.cz>
commit 6ad53f0f71c52871202a7bf096feb2c59db33fc5 upstream.
If rounded block-rounded i_lenExtents matches block rounded i_size,
there are no preallocation extents. Do not bother walking extent linked
list.
