From 1089716f8b5f89d9b85cc2c76b7b59d0c7fbb688 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 25 Mar 2009 09:13:25 -0700 Subject: async_tx: provide __async_inline for HAS_DMA=n archs To allow an async_tx routine to be compiled away on HAS_DMA=n arch it needs to be declared __always_inline otherwise the compiler may emit code and cause a link error.
