[Qemu-devel] [PATCH v6 0/4] qemu-thread: support --enable-debug-mutex

[Peter Xu]

v6:
- rename __QEMU_THREAD_COMMON_H__ to QEMU_THREAD_COMMON_H
- collect r-bs for Emilio

v5:
- init file/line [Emilio]

v4:
- cherrypick Emilio's patch to add "-m" parameter to atomic_add-bench
  tool.
- use inline functions [Emilio]

Micro benchmark result on "taskset -c 0 atomic_add-bench -m":

|--------+---------------------+------------------------|
|        | with --enable-debug | without --enable-debug |
|--------+---------------------+------------------------|
| Before | 20 Mops/s           | 34 Mops/s              |
| After  | 18 Mops/s           | 34 Mops/s              |
|--------+---------------------+------------------------|

Please review.  Thanks.
