From 5a6b7951bfcca7f45f44269ea87417c74558daf8 Mon Sep 17 00:00:00 2001 From: Benjamin LaHaise Date: Thu, 23 Mar 2006 03:01:03 -0800 Subject: [PATCH] get_empty_filp tweaks, inline epoll_init_file() Eliminate a handful of cache references by keeping current in a register instead of reloading (helps x86) and avoiding the overhead of a function call. Inlining eventpoll_init_file() saves 24 bytes. Also reorder file initialization to make writes occur more sequentially.
