Subject: [PATCH v3 17/26] btrfs: make compress_file_range() to be subpage compatible
Date: Mon, 27 Sep 2021 15:21:59 +0800 [thread overview]
Message-ID: <20210927072208.21634-18-wqu@suse.com> (raw)
In-Reply-To: <20210927072208.21634-1-wqu@suse.com>
In function compress_file_range(), when the compression is finished, the
function just round up @total_in to PAGE_SIZE.
This is fine for regular sectorsize == PAGE_SIZE case, but not for
subpage.
Just change the ALIGN(, PAGE_SIZE) to round_up(, sectorsize) so that
both regular sectorsize and subpage sectorsize will be happy.
