findmnt: filter filesystems and actions for --poll
The patch allows to filter by:
* actions name:
$ findmnt --poll=umount
* target, source, fstype, options:
$ findmnt --poll /mnt/test
$ findmnt --poll -O ro
$ findmnt --poll -t ext4
* --first-only option to wait only for the first matching change:
$ findmnt --poll=umount --first-only /mnt/test
