Bug#839081: after suspend (S3) with a rbind-mounted mp3fs: "Transport endpoint is not connected"

[Lukas Pirl]

Package: mp3fs
Version: 0.91-1
Severity: important

Dear Maintainer,

   * What led up to the situation?

(not sure if this is the minimal example)
1. have some mounted file system
   (say a btrfs on /mnt/data)
2. mount mp3fs within that mount point
   (say /mnt/data/music on /mnt/data/music_mp3)
3. rbind (mount) that file system to somewhere else
   (say /mnt/data to /srv/share)
4. suspended (S3) the machine
5. resume the machine
6. try to access /srv/share/music_mp3

   * What was the outcome of this action?

Error "Transport endpoint is not connected" shows up,
no access is possible.

   * What outcome did you expect instead?

Mount works just like before the suspend (i.e. access works w/o errors).

Thanks!
