From c7f404b40a3665d9f4e9a927cc5c1ee0479ed8f9 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Wed, 16 Mar 2011 06:59:40 -0400 Subject: vfs: new superblock methods to override /proc/*/mount{s,info} a) ->show_devname(m, mnt) - what to put into devname columns in mounts, mountinfo and mountstats b) ->show_path(m, mnt) - what to put into relative path column in mountinfo Leaving those NULL gives old behaviour. NFS switched to using those.
