Title:
  camera app is polling the file system every second

Status in camera-app:
  Confirmed
Status in Canonical System Image:
  Confirmed
Status in camera-app package in Ubuntu:
  Confirmed

Bug description:
  from OEM bug #1471310

  running fnotifystat, I can see that every second the camera-app is
  polling away as follows:

  Total Open Close Read Write PID Process Pathname
    8.0 1.0 1.0 6.0 0.0 3175 camera-app /proc/3175/mounts
    2.0 1.0 1.0 0.0 0.0 3175 camera-app /dev/disk/by-label

  Total Open Close Read Write PID Process Pathname
    8.0 1.0 1.0 6.0 0.0 3175 camera-app /proc/3175/mounts
    2.0 1.0 1.0 0.0 0.0 3175 camera-app /dev/disk/by-label

  Total Open Close Read Write PID Process Pathname
    8.0 1.0 1.0 6.0 0.0 3175 camera-app /proc/3175/mounts
    2.0 1.0 1.0 0.0 0.0 3175 camera-app /dev/disk/by-label

  so it is consistently polling away. That's kinda wasteful on resources
  (e.g. battery drain).
