Linus, Al, Eric,

This small series implement the exact-match comparison ahead of the
case-insensitive comparison as suggested by Linus.  The first patch only
exposes dentry_string_cmp in a header file so we can use it instead of
memcmp and the second actually do the optimization in the
case-insensitive comparison code.

Gabriel Krisman Bertazi (2):
  dcache: Expose dentry_string_cmp outside of dcache
  libfs: Attempt exact-match comparison first during casefold lookup
