If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Jean Delvare commit fd7f6727102a1ccf6b4c1dfcc631f9b546526b26 upstream. I don't think it makes sense for a module to have a soft dependency on itself. This seems quite cyclic by nature and I can't see what purpose it could serve. OTOH libcrc32c calls crypto_alloc_shash("crc32c", 0, 0) so it pretty much assumes that some incarnation of the "crc32c" hash algorithm has been loaded. Therefore it makes sense to have the soft dependency there (as crc-t10dif does.) Cc: Tim Chen Cc: "David S.
