From: Ben Hutchings <bhutchings@...arflare.com>
To: Jeff Garzik <jgarzik@...ox.com>
Cc: netdev@...r.kernel.org, linux-net-drivers@...arflare.com
Subject: [PATCH 20/52] sfc: Removed forced inlining of long functions
gcc will automatically inline static functions with only one caller, and
may inline other functions depending on the kernel configuration and size
of the intermediate code.
