Message-Id: <1367348080-4680-1-git-send-email-sasha.levin@oracle.com> Date: Tue, 30 Apr 2013 14:54:31 -0400 From: Sasha Levin <sasha.levin@...cle.com> To: torvalds@...ux-foundation.org Cc: mingo@...nel.org, peterz@...radead.org, linux-kernel@...r.kernel.org, Sasha Levin <sasha.levin@...cle.com> Subject: [PATCH 0/9] liblockdep: userspace lockdep liblockdep is a tiny wrapper built around kernel/lockdep.c. The aim is to provide the same functionality the kernel gets from lockdep to userspace. The bulk of the code here is the LD_PRELOAD support which provides users an easy way to test their code without having to integrate liblockdep into said code. Simply doing: lockdep my_app Would provide lockdep support to my_app. There is also a small test suite to test both mutexes and rwlocks, it's based on the tests in lib/locking-selftest.c. This entire patch series was reviewed by lockdep maintainers and accepted to the tip tree previously. It was pulled out so that the potential merge of liblockdep won't delay the rest of the commits in the tip locking tree. For some more background about this entire thing, the folks at LWN did an awesome overview: http://lwn.net/Articles/536363/ Sasha Levin (9): lockdep: Be nice about building from userspace liblockdep: Wrap kernel/lockdep.c to allow usage from userspace liblockdep: Add public headers for pthread_mutex_t implementation liblockdep: Add pthread_mutex_t test suite liblockdep: Add public headers for pthread_rwlock_t implementation liblockdep: Add pthread_rwlock_t test suite liblockdep: Support using LD_PRELOAD liblockdep: Add the 'lockdep' user-space utility liblockdep: Add a MAINTAINERS entry
