Git-commit: 83fe9e12b0558eae519351cff00da1e06bc054d2
Patch-mainline: 5.8-rc1
References: bsc#1176019
Subject: [PATCH] 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.
