-CRUSH hash algorithm.  This is a consistent hash

-during directory restripe.
+.B all_char (type 1)
+Sum of ASCII characters modulo number of MDTs. This

 Fowler-Noll-Vo (FNV-1a) hash algorithm.  This provides
 reasonably uniform, but not cryptographically strong,
 hashing of the filename. (default)
