From 5d3851530d6d68564e4e0ce04d0547d4d106fc72 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 28 Nov 2011 10:40:46 -0800 Subject: 9p: Reduce object size with CONFIG_NET_9P_DEBUG Reduce object size by deduplicating formats. Use vsprintf extension %pV. Rename P9_DPRINTK uses to p9_debug, align arguments. Add function for _p9_debug and macro to add __func__. Add missing "\n"s to p9_debug uses. Remove embedded function names as p9_debug adds it. Remove P9_EPRINTK macro and convert use to pr_. Add and use pr_fmt and pr_. $ size fs/9p/built-in.o* text data bss dec hex filename 62133 984 16000 79117 1350d fs/9p/built-in.o.new 67342 984 16928 85254 14d06 fs/9p/built-in.o.old $ size net/9p/built-in.o* text data bss dec hex filename 88792 4148 22024 114964 1c114 net/9p/built-in.o.new 94072 4148 23232 121452 1da6c net/9p/built-in.o.old Signed-off-by: Joe Perches Signed-off-by: Eric Van Hensbergen --- fs/9p/cache.c | 64 +++++++++++++++++++++++++++++------------------------------ 1 file changed, 32 insertions(+), 32 deletions(-) (limited to 'fs/9p/cache.c') diff --git a/fs/9p/cache.c b/fs/9p/cache.c index 945aa5f02f9b..a9ea73d6dcf3 100644 --- a/fs/9p/cache.c +++ b/fs/9p/cache.c @@ -62,8 +62,8 @@ static uint16_t v9fs_cache_session_get_key(const void *cookie_netfs_data, uint16_t klen = 0;
