## NAME
       /proc/pid/mountstats - mount statistics

## DESCRIPTION
       _/proc/_pid_/mountstats_ (since Linux 2.6.17)
              This file exports information (statistics, configuration information) about the mounts
              in  the  process's mount namespace (see [**mount_namespaces**(7)](https://www.chedong.com/phpMan.php/man/mountnamespaces/7/markdown)).  Lines in this file have
              the form:

                  device /dev/sda7 mounted on /home with fstype ext3 [stats]
                  (       1      )            ( 2 )             (3 ) (  4  )

              The fields in each line are:

              (1)  The name of the mounted device (or "nodevice" if there is  no  corresponding  de‐
                   vice).

              (2)  The mount point within the filesystem tree.

              (3)  The filesystem type.

              (4)  Optional  statistics  and  configuration  information.   Currently  (as  at Linux
                   2.6.26), only NFS filesystems export information via this field.

              This file is readable only by the owner of the process.
