proc_pid_mounts(5) File Formats Manual proc_pid_mounts(5)
/proc/pid/mounts - mounted filesystems
/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 descriptor 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).
