From c45d286e72dd72c0229dc9e2849743ba427fee84 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 28 Mar 2007 14:29:08 -0700 Subject: [NET]: Inline net_device_stats Network drivers which keep stats allocate their own stats structure then write a get_stats() function to return them. It would be nice if this were done by default. 1) Add a new "stats" field to "struct net_device". 2) Add a new feature field to say "this driver uses the internal one" 3) Have a default "get_stats" which returns NULL if that feature not set. 4) Change callers to check result of get_stats call for NULL, not if ->get_stats is set. This should not break backwards compatibility with older drivers, yet allow modern drivers to shed some boilerplate code. Lightly tested: works for a modified lguest network driver.

Miller" Date: Tue, 10 Apr 2007 22:10:39 -0700 Subject: [S390]: Fix build on 31-bit. Allow s390 to properly override the generic __div64_32() implementation by: 1) Using obj-y for div64.o in s390's makefile instead of lib-y 2) Adding the weak attribute to the generic implementation.
