Subject: lockdep: Make print_lock() address visible
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=519248f36d6f3c80e176f6fa844c10d94f1f5990;p=openwrt%2Fstaging%2Fblogic.git

lockdep: Make print_lock() address visible

Security is a wonderful thing, but so is the ability to debug based on
lockdep warnings.  This commit therefore makes lockdep lock addresses
visible in the clear.
