... so that they can be copied with struct assignment (which generates better code) and accessed word-by-word. The type is union shortname_storage; it's a union of arrays of unsigned char and unsigned long. struct name_snapshot.inline_name turned into union shortname_storage; users (all in fs/dcache.c) adjusted. struct dentry.d_iname has some users outside of fs/dcache.c; to reduce the amount of noise in commit, it is replaced with union shortname_storage d_shortname and d_iname is turned into a macro that expands to d_shortname.string (similar to d_lock handling). That compat macro is temporary - most of the remaining instances will be taken out by debugfs series, and once that is merged and few others are taken care of this will go away.
