Subject: RCU callback and scheduling while atomic!
Date: Tue, 31 Aug 2004 18:17:10 +0200 [thread overview]
Message-ID: <20040831161710.GA21782@MAIL.13thfloor.at> (raw)
Hi Dipankar!
Hi Rusty!
just a short question regarding RCU callbacks:
it seems that the RCU callback is not allowed
to (re-)schedule, as it is done occasionally by
put_namespace() for example, as I keep getting
"bad: scheduling while atomic!", when I do so ...
now the question: what is the 'correct' way to
drop a reference to a namespace when freeing up
a structure from an RCU callback?
TIA,
Herbert
