 ## Linux distribution status
+
 Starting with Linux kernel 4.18, the SMB kernel module, called `cifs` for legacy reasons, exposes a new module parameter (often referred to as *parm* by various external documentation) called `disable_legacy_dialects`. Although introduced in Linux kernel 4.18, some vendors have backported this change to older kernels that they support. The following table details the availability of this module parameter on common Linux distributions.

 Before disabling SMB 1, confirm that the SMB module isn't currently loaded on your system (which happens automatically if you've mounted an SMB share). Run the following command, which should output nothing if SMB isn't loaded:
