Subject: queue_work from interrupt Real time preemption2.6.11-rc2-RT-V0.7.37-03
Date: Mon, 14 Feb 2005 12:40:14 -0800 [thread overview]
Message-ID: <200502141240.14355.mgross@linux.intel.com> (raw)
I'm working on a tweak to the preepmtive soft IRQ implementation using work
queues and I'm having problems with a BUG assert when trying to queue_work.
Souldn't I be able to call queue_work form ISR context?
