NAME

   /proc/pid/mounts - mounted filesystems

DESCRIPTION

   /proc/pid/mounts (since Linux 2.4.19)
          This file lists all the filesystems currently mounted in the process's mount namespace (see mount_namespaces(7)).  The format of this file is documented in fstab(5).

          Since Linux 2.6.15, this file is pollable: after opening the file for reading, a change in this file (i.e., a filesystem mount or unmount) causes select(2) to mark the file de‐
          scriptor  as having an exceptional condition, and poll(2) and epoll_wait(2) mark the file as having a priority event (POLLPRI).  (Before Linux 2.6.30, a change in this file was
          indicated by the file descriptor being marked as readable for select(2), and being marked as having an error condition for poll(2) and epoll_wait(2).)

   /proc/mounts
          Before Linux 2.4.19, this file was a list of all the filesystems currently mounted on the system.  With the introduction of per-process mount namespaces in  Linux  2.4.19  (see
          mount_namespaces(7)),  this  file  became  a  link  to /proc/self/mounts, which lists the mounts of the process's own mount namespace.  The format of this file is documented in
          fstab(5).
