[9fans] How to kill a process

[Adriano Verardo <adriano.verardo@mail.com>]

Hi, all.

Five years ago I wrote the manager for a USB barcode reader.
Basically a derivative of the keyboard mngr, but not embedded in usbd.
Recently has been noted that after a unplug-plug of the reader, the
kernel recognizes
the reader (apparently) as usual but the mounted root of the manager is
empty.

The reason seems to be a spuriuos instance of the manager, impossible to
kill
with kill and slay too. In fact, after a reboot all works again.
Both manager and application have been never changed while the
kernel stuff is updated weekly (replica/pull).

IMHO something changed in the interface between usbd and external managers.

  Is it possible ?

In what condition a process started by usbd becomes not killable ?

Thanks in advance.
