Subject: RE: [PATCH v7 00/13] ksmbd: introduce new SMB3 kernel server
Date: Thu, 5 Aug 2021 15:23:03 +0900	[thread overview]

> ===============
> 
> The SMB family of protocols is the most widely deployed network filesystem protocol, the default on
> Windows and Macs (and even on many phones and tablets), with clients and servers on all major
> operating systems, but lacked a kernel server for Linux. For many cases the current userspace server
> choices were suboptimal either due to memory footprint, performance or difficulty integrating well
> with advanced Linux features.

> ksmbd is a new kernel module which implements the server-side of the SMB3 protocol.
> The target is to provide optimized performance, GPLv2 SMB server, better lease handling (distributed
> caching). The bigger goal is to add new features more rapidly (e.g. RDMA aka "smbdirect", and recent
> encryption and signing improvements to the protocol) which are easier to develop on a smaller, more
> tightly optimized kernel server than for example in Samba.  The Samba project is much broader in scope
> (tools, security services, LDAP, Active Directory Domain Controller, and a cross platform file server
> for a wider variety of purposes) but the user space file server portion of Samba has proved hard to
> optimize for some Linux workloads, including for smaller devices. This is not meant to replace Samba,
> but rather be an extension to allow better optimizing for Linux, and will continue to integrate well
> with Samba user space tools and libraries where appropriate.
> Working with the Samba team we have already made sure that the configuration files and xattrs are in a
> compatible format between the kernel and user space server.

I missed updating test result in cover letter.
