Subject: [PATCH v2 0/3] trace: Use simpler seq_file functions
Date: Sat, 8 Nov 2014 21:42:09 +0100 [thread overview]
Message-ID: <1415479332-25944-1-git-send-email-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <1410513954-28909-5-git-send-email-linux@rasmusvillemoes.dk>
Using printf to print a simple string or puts to print a single
character is more expensive than it needs to be. Also, consecutive
puts calls can be replaced by a single call. These patches do this to
kernel/trace/, saving ~256 bytes of .text.
v2: Keep the original splitting of strings across lines.
Rasmus Villemoes (3):
trace: Replace seq_printf by simpler equivalents
trace: Merge consecutive seq_puts calls
trace: Replace single-character seq_puts with seq_putc
