The latter. Sorry, I meant to imply that whan I said that the directories
hadn't been modified for years (= longer than the metadata_chum feature has
been in the kernel).

Here's some sample output. Note that the machine has been rebooted
to install 7.6.2 since my last e-mail, which forced an fsck, although
that's far from the first fsck since e2fsprogs_1.43~WIP was installed;
I had already tried e2fsck -D as recommended before posting.
Kernel errors from previous boot:
EXT4-fs error (device md5): ext4_dirent_csum_verify:262: inode #7260289: comm nfsd: metadata_csum set but no space in dir leaf for checksum. Please run e2fsck -D.
EXT4-fs error (device md5): ext4_find_entry:1217: inode #7260289: comm nfsd: checksumming directory block 0
(I haven't got any such messages this boot yet.)
