Date: Tue, 28 May 2013 16:48:26 +0200 From: Maarten Lankhorst <maarten.lankhorst@...onical.com> To: linux-kernel@...r.kernel.org Cc: linux-arch@...r.kernel.org, peterz@...radead.org, x86@...nel.org, dri-devel@...ts.freedesktop.org, linaro-mm-sig@...ts.linaro.org, robclark@...il.com, rostedt@...dmis.org, daniel@...ll.ch, tglx@...utronix.de, mingo@...e.hu, linux-media@...r.kernel.org Subject: [PATCH v4 0/4] add mutex wait/wound/style style locks Version 4 already? Small api changes since v3: - Remove ww_mutex_unlock_single and ww_mutex_lock_single. - Rename ww_mutex_trylock_single to ww_mutex_trylock. - Remove separate implementations of ww_mutex_lock_slow*, normal functions can be used. Inline versions still exist for extra debugging, and to annotate. - Cleanup unneeded memory barriers, add comment to the remaining smp_mb(). Thanks to Daniel Vetter, Rob Clark and Peter Zijlstra for their feedback. --- Daniel Vetter (1): mutex: w/w mutex slowpath debugging Maarten Lankhorst (3): arch: make __mutex_fastpath_lock_retval return whether fastpath succeeded or not. mutex: add support for wound/wait style locks, v5 mutex: Add ww tests to lib/locking-selftest.c. v4 Documentation/ww-mutex-design.txt | 344 +++++++++++++++++++++++++++++++ arch/ia64/include/asm/mutex.h | 10 - arch/powerpc/include/asm/mutex.h | 10 - arch/sh/include/asm/mutex-llsc.h | 4 arch/x86/include/asm/mutex_32.h | 11 - arch/x86/include/asm/mutex_64.h | 11 - include/asm-generic/mutex-dec.h | 10 - include/asm-generic/mutex-null.h | 2 include/asm-generic/mutex-xchg.h | 10 - include/linux/mutex-debug.h | 1 include/linux/mutex.h | 363 +++++++++++++++++++++++++++++++++ kernel/mutex.c | 384 ++++++++++++++++++++++++++++++++--- lib/Kconfig.debug | 13 + lib/debug_locks.c | 2 lib/locking-selftest.c | 410 +++++++++++++++++++++++++++++++++++-- 15 files changed, 1492 insertions(+), 93 deletions(-) create mode 100644 Documentation/ww-mutex-design.txt -- ~Maarten -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
