Subject: lockdep: use WARN() in kernel/lockdep.c
X-Git-Tag: v2.6.27-rc4~50^2~1
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=2df8b1d656021e180ab93c8a4b2c9c2923d30b82;p=linux-2.6-omap-h63xx.git

lockdep: use WARN() in kernel/lockdep.c

Use WARN() instead of a printk+WARN_ON() pair; this way the message
becomes part of the warning section for better reporting/collection.
