[PATCH 5.4 507/658] cifs: fix missing display of three mount options

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Steve French <stfrench@xxxxxxxxxxxxx>

commit 2bfd81043e944af0e52835ef6d9b41795af22341 upstream.

Three mount options: "tcpnodelay" and "noautotune" and "noblocksend"
were not displayed when passed in on cifs/smb3 mounts (e.g. displayed
in /proc/mounts e.g.).  No change to defaults so these are not
displayed if not specified on mount.
