Phoronix: KSMBD As An In-Kernel SMB3 File Server Merged For Linux 5.15

One of the earliest pull requests sent in for the now-open Linux 5.15 cycle was proposing KSMBD land as the in-kernel SMB3 file server as an alternative on Linux systems to running Samba in user-space. At the time it wasn't clear if Linus Torvalds would pull in this file server code to the Linux kernel but now he has indeed landed it...

i hope if its done we can use it like nfs or http/s for pxe

What functionality would smb in the kernel give us I thought they moved it to the kernel because it would be faster but not give you more features

cytomax55 u dont need samba for easy file share as user

You don't need in-kernel performance either.

Any speed improvement is welcome.......

Oh cool so you can share files without setting up a Saba server like I'm Windows... That's pretty neat

Hmm... pretty sure network file systems are restricted by the speed/latency of the network, not by the code being in user space... but hey - why not stick this in the kernel too?

Actually, weak devices struggle to match even 1GbE connections. This could help them.

A server in the kernel?! This is insane in my opinion! This is contra security and maintainability!
