Subject: [PATCH 04/11] btrfs: move ordered_extent internal sanity checks into btrfs_split_ordered_extent
Date: Fri, 24 Mar 2023 10:32:00 +0800 [thread overview]
Message-ID: <20230324023207.544800-5-hch@lst.de> (raw)
In-Reply-To: <20230324023207.544800-1-hch@lst.de>
Move the three checks that are about ordered extent internal sanity checking
into btrfs_split_ordered_extent instead of doing them in the higher level
btrfs_extract_ordered_extent routine.
Signed-off-by: Christoph Hellwig <hch@lst.de>
