[Qemu-devel] [PATCH for-2.10 0/9] RBD reopen, read_only cleanup

From: Jeff Cody
Subject: [Qemu-devel] [PATCH for-2.10 0/9] RBD reopen, read_only cleanup
Date: Wed, 5 Apr 2017 14:28:42 -0400

This series does two things:

1.) Cleans up some of the logic behind setting the read_only flag
    for a BDS in the block layer, so that it is done consistently
    (and rules are applied consistently), and

2.) Adds .bdrv_reopen_prepare() implementation for RBD, so that block
    jobs can be run on backing chains that have rbd protocol nodes.

Jeff Cody (9):
  block: add bdrv_set_read_only() helper function
  block: do not set BDS read_only if copy_on_read enabled
  block: honor BDRV_O_ALLOW_RDWR when clearing bs->read_only
  block: code movement
  block: introduce bdrv_try_set_read_only()
  block: use bdrv_try_set_read_only() during reopen
  block/rbd - update variable names to more apt names
  block/rbd: do not blindly set bs->read_only
  block/rbd: Add support for reopen()
