[Qemu-block] [PATCH v14 00/20] block: Image locking series


From: Fam Zheng
Subject: [Qemu-block] [PATCH v14 00/20] block: Image locking series
Date: Fri, 21 Apr 2017 11:55:46 +0800

v14: - Replace BDRV_ flag with the "force-shared-write" block option. [Kevin]
     - Add bs->force_shared_write.
     - Update test case accordingly, back to bash again. :)
     - A few fixes in the locking code spotted by patchew and the new test,
       though the long line error is still there for readability.
     - Replace the workaround to drive-backup with a real fix in patch 17.

v13: - Address Max's comments.
     - Add reviewed-by from Max and Eric.
     - Rebase for 2.10:
       * Use op blocker API
       * Add --unsafe-read for qemu-img and qemu-io
