6333409 traversal code should be able to issue multiple reads in parallel 6418042 want traversal in depth-first pre-order for quicker 'zfs send' 6757112 zvol dump code is extra complicated 6725668 want ::zfs_blkstats to show block type stats after scrub 6725675 dmu traverse code has extraneous features 6725680 P2CROSS is confusing to use 6725698 zvol dump device should always be 128k 6729696 sync causes scrub or resilver to pause for up to 30s 6730101 online recv can cause scrub to miss some blocks 6752226 assertion failed in dbuf_verify: db->db.db_size >= dn->dn_datablksz 6577985 panic when zfs send a snapshot with i/o errors 6755042 zdb -Lbc counts block several times in case of checksum errors
