Hi, the $subj warning appears sometimes in syslog, in my case when xfstests/209 runs looped. The minimal reproducer is looped mkfs+mount. The message comes from disk-io.c btree_readpage_end_io_hook(): 581 if (check_tree_block_fsid(root, eb)) { 582 printk_ratelimited(KERN_INFO "btrfs bad fsid on block %llu\n", 583 (unsigned long long)eb->start); 584 ret = -EIO; 585 goto err; 586 } rele...

This series introduces a generic readahead interface for btrfs trees. The intention is to use it to speed up scrub in a first run, but balance is another hot candidate. In general, every tree walk could be accompanied by a readahead. Deletion of large files comes to mind, where the fetching of the csums takes most of the time.
