Hello Mr. Thibault,
thanks for the reply.
I guess you have tested this on a bz2-backed filesystem?
I tested with various size .bz2 files (to be clear: "settrans -ca test
/hurd/storeio -T typed bunzip2:file:test.bz2").
Do I need to do another kind of tests? I'll be happy to check other
things to
Assertions were added instead of silently returning from functions
on errors and private futexes were simplified.
This is one of the last versions. I won't be changing the base code,
except for fixing bugs if they are found, as this actually works as
expected. I'm little bit unsure about the cor

To detect if an active translator goes away, we need to register for
dead name notifications. Those notifications have to be sent to a port
known to the ports library, as the ports library handles the dead name
notifications. The most straight forward way is to use the port to the
underlying node f

Traditionally, /proc/mounts includes only filesystem mount points.
Previously though, the mtab translator included any kind of
translator, like all /hurd/storeio translators. This causes problems
with umount --all as this would remove the passive translator records
from nodes in /dev.
Fix this by

Previously the mtab detector tried to detect whether it talks to
itself by comparing the control port of the translator it currently
visits with its own. This was done to prevent deadlocks. However, this
did not detect non-trivial loops, i.e. two mtab translators would
still dead-lock each other.
Previously the mtab content was generated in the open hook. Delay this
until the data is needed. A follow up patch will take advantage of
this to both simplify the logic in mtab_populate and make it more
robust at the same time.
* trans/mtab.c (open_hook): Do not eagerly populate the mtab.
