This adds a case insensitive hash function to allow taking the hash without needing to allocate a casefolded copy of the string. Signed-off-by: Daniel Rosenberg <drosen@google.com> Test: Boots, /data/media is case insensitive Bug: 138322712 Link: https://lore.kernel.org/linux-f2fs-devel/20200208013552.241832-1-drosen@google.com/T/#t Change-Id: I43c7d38a8e22f4479397f35e6343bd326901cdba
