you are correct, I added some debug output to the kernel itself (in
fs/file_table.c) to log the inode number that causes sys_mount to return
The inode in my case was reported as 5669195 which according to the lsof
log is exactly the mapping you suspected:
plymouthd 3101 0 mem REG 8,5 1
It seems to be part of d-conf.

I arrived here from bug 963106
[https://bugs.launchpad.net/bugs/963106]. I thought that it was a
problem with network-manager, but it was not.
I was suggested that it is probably a problem with upstart : "that
modemmanager simply hasn't had time to complete the shutdown process
before umountroot is run. Since modemmanager is an upstart job,
sendsigs doesn't kill it."
