Subject: [PATCH 7/7] udf: Keep i_lenExtents consistent with the total length of extents
Date: Thu, 22 Dec 2022 11:16:04 +0100	[thread overview]
Message-ID: <20221222101612.18814-7-jack@suse.cz> (raw)
In-Reply-To: <20221222101300.12679-1-jack@suse.cz>

When rounding the last extent to blocksize in inode_getblk() we forgot
to update also i_lenExtents to match the new extent length. This
inconsistency can later confuse some assertion checks.
