Date: Wed, 6 Dec 2006 17:33:16 -0600 From: linas@...tin.ibm.com (Linas Vepstas) To: Andrew Morton <akpm@...l.org> Cc: jgarzik@...ox.com, netdev@...r.kernel.org, linuxppc-dev@...abs.org, James K Lewis <jklewis@...ibm.com>, Arnd Bergmann <arnd@...db.de>, Geoff Levand <geoffrey.levand@...sony.com> Subject: [PATCH 4/16] Spidernet Refactor RX refill Refactor how spider_net_refill_rx_chain() is called. No functional change; this just simplifies the code by moving the subroutine call to a more appropriate spot.
