From 34e49d4f635d6a800c4089c40fd254e12e451449 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Wed, 12 Jan 2011 17:00:30 -0800 Subject: [PATCH] fs/proc/base.c, kernel/latencytop.c: convert sprintf_symbol() to %ps Use temporary lr for struct latency_record for improved readability and fewer columns used. Removed trailing space from output.
