From c7141d005a19d2a0a316b3bf9c170d3bedf07bfd Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 17 Jul 2008 17:59:56 -0700 Subject: iop_adma: directly reclaim descriptors on allocation failure Force callers that trigger an "out of descriptors" condition to run the cleanup loop directly. Alleviates the requirement to have soft-irqs enabled when polling for a descriptor in async_xor.
