Subject: btrfs: block-group: don't set the wrong READA flag for btrfs_read_block_groups()
X-Git-Tag: timers-urgent-2020-06-11~6^2~53

btrfs: block-group: don't set the wrong READA flag for btrfs_read_block_groups()

Regular block group items in extent tree are scattered inside the huge
tree, thus forward readahead makes no sense.
