The use of the term "glue" in filenames is a Crypto API-ism that rarely shows up elsewhere in lib/ or arch/*/lib/. I think adopting it there was a mistake. The library just uses standard functions, so the amount of code that could be considered "glue" is quite small. And while often the C functions just wrap the assembly functions, there are also cases like crc32c_arch() in arch/x86/lib/crc32-glue.c that blur the line by in-lining the actual implementation into the C function. That's not "glue code", but rather the actual code. Therefore, let's drop "glue" from the filenames and instead use e.g. crc32.c instead of crc32-glue.c. Reviewed-by: "Martin K.
