Cover letter [PATCH 0/3] ksmbd: More crypto library conversions
This series converts fs/smb/server/ to access SHA-512, HMAC-SHA256, and HMAC-MD5 using the library APIs instead of crypto_shash.
This simplifies the code significantly. It also slightly improves performance, as it eliminates unnecessary overhead. I haven't done server-specific benchmarks, but you can get an idea of what to expect by looking at the numbers I gave for the similar client-side series:
https://lore.kernel.org/linux-cifs/20251014034230.GC2763@sol/
No change in behavior intended. All the crypto computations should be the same as before. I haven't tested this series (I did test the similar client-side series), but everything should still work.

ksmbd: Use HMAC-SHA256 library for message signing and key generation
ksmbd: Use HMAC-MD5 library for NTLMv2
