This allows to flush dcache entries of a task on multiple procfs mounts

The RCU lock is used because the number of reads at the task exit time

Ok, this looks better to me than the previous version.

But that may be the "pee-in-the-snow" effect, and I _really_ want
others to take a good look at the whole series.

The right people seem to be cc'd, but this is pretty core, and /proc
has a tendency to cause interesting issues because of how it's
involved in a lot of areas indirectly.
