12 The Linux SMB kernel client supports SMB Direct, which is a transport
16 SMB Direct on the Linux SMB client can be tested against KSMBD - a
17 kernel-space SMB server.
25 - Install a kernel with SMB Direct support. The first kernel release to
26 support SMB Direct on both the client and server side is 5.15. Therefore,
29 - Install cifs-utils, which provides the `mount.cifs` command to mount SMB
54 - Enable SMB Direct support for both the server and the client in the kernel
