From b4758165fe80041d797687f58e94b08bfbae3fd4 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 21 Dec 2011 16:48:08 -0500 Subject: net: Add a flow_cache_flush_deferred function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit c0ed1c14a72ca9ebacd51fb94a8aca488b0d361e ] flow_cach_flush() might sleep but can be called from atomic context via the xfrm garbage collector. So add a flow_cache_flush_deferred() function and use this if the xfrm garbage colector is invoked from within the packet path.
