make sure that DNAME_INLINE_LEN is a multiple of word size
... calling the number of words DNAME_INLINE_WORDS.
The next step will be to have a structure to hold inline name arrays
(both in dentry and in name_snapshot) and use that to alias the
existing arrays of unsigned char there. That will allow both
full-structure copies and convenient word-by-word accesses.
