The format of this file is documented in fstab(5).\n\nSince  Linux  2.6.15,  this  file  is  pollable: after opening the file for reading, a\nchange in this file (i.e., a filesystem mount or unmount) causes select(2) to mark the\nfile descriptor as having an exceptional condition, and poll(2) and epollwait(2) mark\nthe file as having a priority event (POLLPRI).  (Before Linux 2.6.30, a change in this\nfile was indicated by the file descriptor being marked as readable for select(2),  and\nbeing marked as having an error condition for poll(2) and epollwait(2).)\n\n/proc/mounts\nBefore  Linux 2.4.19, this file was a list of all the filesystems currently mounted on\nthe system.  With the introduction of per-process mount  namespaces  in  Linux  2.4.19\n(see  mountnamespaces(7)),  this file became a link to /proc/self/mounts, which lists\nthe mounts of the process's own mount namespace.  The format of  this  file  is  docu‐\nmented in fstab(5).\n",
