Subject: [PATCH 4/6] IB/ehca: remove _irqsave, move #ifdef
Date: Wed, 9 May 2007 13:48:20 +0200 [thread overview]
Message-ID: <200705091348.20808.fenkes@de.ibm.com> (raw)
- In ehca_process_eq(), we're IRQ safe throughout the whole function, so we
don't need another _irqsave in the middle of flight.
- take_over_work() is only called by comp_pool_callback(), so it can move
into the same #ifdef block.
