Hi,
I just hit a XFS crash [1] when I tested XFS on a 500T storage. And a XFS
corruption [2] can be found by "xfs_repair -n".
Tested on 4.17-rc6, xfsprogs-4.16.1. mkfs.xfs options are "-m crc=1,finobt=1,
rmapbt=1,reflink=1 -i sparse=1".
I've report a bug as below:

Maybe it's time I cleaned up & sent out my patch that dumps the data and
cow forks to ftrace when we hit this assert.
Also, I think i_dlayed_blks should be xfs_filblks_t, not unsigned int...
