Thanks for tracking it down! After a fsck, I'm still seeing fs corruption,
unfortunately:
[177266.375628] EXT4-fs error (device dm-1): htree_dirblock_to_tree:586: inode
#12255304: block 88074025: comm rm: bad entry in directory: rec_len is smaller
than minimal - offset=0(4096), inode=0, rec_len=0, name_len=0
[177266.375872] EXT4-fs error (device dm-1): htree_dirblock_to_tree:586: inode

[177266.376360] EXT4-fs error (device dm-1): empty_dir:1922: inode #12255304:
block 88074026: comm rm: bad entry in directory: rec_len is smaller than
minimal - offset=0(8192), inode=0, rec_len=0, name_len=0
fsck didn't notice this problem, but walking the tree seems to trigger it. I've
been trying to clean it up by just removing the offending directory, but it I
figured I'd mention it since it seems to be a problem that fsck -f didn't see.
