As I know, ksmbd is enable in 5.15 kernel of some distros(opensuse, ubuntu, etc) except redhat. And users can use this feature. I will make the time for ksmbd backporting job. To facilitate backport, Can I submit clean-up patches for ksmbd of 5.15 kernel or only bug fixes are allowed? Thanks. > > thanks, > > greg k-h >
