From 2cf83afe902fd72ef4b211774e48ab39890fb328 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Sun, 13 Apr 2008 21:54:34 -0700 Subject: [ATM] drivers/atm/horizon.c: stop inlining largish static functions drivers/atm/horizon.c has unusually large number of static inline functions - 36. I looked through them. Most of them seems to be small enough, but a few are big, others are using udelay or busy loop, and as such are better not be inlined. This patch removes "inline" from these static functions (regardless of number of callsites - gcc nowadays auto-inlines statics with one callsite).
