I now have a patch to reject these invalid inode log formats gracefully.  That
will still make the log recovery for a fs as badly damaged as yours fail, but
at least it will prevent the kernel from crashing and give some useful error
instead.

FYI, I just dumped the whole structures and it's almost completely zeroed:

[   20.115521] XFS: bad number of regions (0) in inode log item
[   20.136952] ilf_fields = 0x2, ilf_asize = 0, ilf_dsize = 0
[   20.148272] ilf_ino = 0, ilf_blkno = 0
[   20.159309] ilf_len = 0, ilf_boffset = 0

xfs_logprint also finds various invalid zeroes over the log.

Was this filesystem written ontop of luks?  In that case I suspect it's doing
something very weird with the write I/Os which causes this log corruption.
