Subject: [PATCH 04/27] btrfs: don't pass compressed pages to btrfs_writepage_endio_finish_ordered()
Date: Tue, 13 Jul 2021 14:14:53 +0800 [thread overview]
Message-ID: <20210713061516.163318-5-wqu@suse.com> (raw)
In-Reply-To: <20210713061516.163318-1-wqu@suse.com>
Since async_extent holds the compressed page, it would trigger the new
ASSERT() in btrfs_mark_ordered_io_finished() which checks the range is
inside the page.
Now btrfs_writepage_endio_finish_ordered() can accept @page == NULL,
just pass NULL to btrfs_writepage_endio_finish_ordered().
