Built from a pull around midnight EST last night.
(Don't have the git hash, as the source is on the disk that is now inaccessable..)

EXT4-fs error (device sdb1): htree_dirblock_to_tree:919: inode #172235804: block 152052301: comm ls: bad entry in directory: rec_len is smaller than minimal - offset=0(0), inode=0, rec_len=0, name_len=0

This is a 3TB disk which has 1.9TB used.

I can see some files/dirs, but some top level dirs now appear empty.

About to reboot back to a safe kernel and fsck.
