or

$ jc /proc/1/mountinfo

or

$ cat /proc/1/mountinfo | jc --proc-pid-mountinfo

Usage (module):

import jc
result = jc.parse('proc', proc_pid_mountinfo_file)

or

import jc
result = jc.parse('proc_pid_mountinfo', proc_pid_mountinfo_file)

Schema:

[
  {
    "mount_id":                 integer,
    "parent_id":                integer,
    "maj":                      integer,
    "min":                      integer,
    "root":                     string,
    "mount_point":              string,
    "mount_options": [
                                string

    "super_options_fields": {
      "<key>":                  string
    }
  }
]

[0] if empty, then private mount
[1] unbindable will always have a value of 0
[2] integer conversions are attempted. Use --raw or raw=True for
    original string values.
