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 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).
