  ksmbd: increase session and share hash table bits (2025-09-30 21:37:55 -0500)

----------------------------------------------------------------
Nine ksmbd server fixes
- Fix potential UAFs and corruptions in rpc open and close
- Fix copy_file_range when ranges overlap
- Improve session, share, connection lookup performance
- Fix potential hash collisions in share and session lists
- Debugging improvement - making per-connection threads easier to identify
- Improve socket creation
- Fix return code mapping for posix query fs info
- Two patches add support for limiting the maximum number of
connections per IP address, extending the existing connection limiting
mechanism to enforce per-IP connection limits alongside the global
connection limit
