The routines are small enough, less than 500 loc total, that it would not
make a whole lot of difference either way. Although I noticed a few
different places where MD5 is implemented in other parts of the kernel, the
HMAC-MD5 support (in md5.c) needed for signing smb frames is probably not
needed by anyone else (except PPP?). I did not see any places (other than
cifs) that depend on md4 so that seems like it would not make sense to move
even though the code is pretty generic. The ASN decoding routines on the
other hand (used e.g. by snmp and also will be needed in the future by the
cifs vfs for simple SPNEGO-like parsing of the session establishment frame)
might end up being useful to move into a common library in the long run.
