debugging pseudo-file - viewing open file list from client

[Steve French]

Was thinking about json a little more - looks like no kernel examples
(other than user space tools that produce, not consume from the
kernel) json (see e.g. "jsonw_printf")

More machine readable examples in debug output do exist - maybe format
more like an xfs example (see below), keep the output terse and then
we can let the proposed smbinfo (smb3info or whatever) dump this is
human readable form:

# cat /proc/fs/xfs/stat
extent_alloc 0 0 0 0
abt 0 0 0 0
blk_map 0 0 0 0 0 0 0
bmbt 0 0 0 0
dir 0 0 0 0
