Subject: [PATCH v4 1/7] btrfs: block-group: Don't set the wrong READA flag for btrfs_read_block_groups()
Date: Tue, 5 May 2020 07:58:19 +0800 [thread overview]
Message-ID: <20200504235825.4199-2-wqu@suse.com> (raw)
In-Reply-To: <20200504235825.4199-1-wqu@suse.com>
For regular block group items in extent tree, they are scattered inside
the huge tree, thus forward readahead makes no sense.
