Subject: [Qemu-devel] [PATCH 0/4] block: Fix permission during reopen
Date: Fri, 9 Mar 2018 16:09:06 +0800 [thread overview]
Message-ID: <20180309080910.7274-1-famz@redhat.com> (raw)
We write open the whole backing chain during reopen. It is not necessary and
will cause image locking problems if the backing image is shared.
Fam Zheng (4):
block: Pass "current_flags" in BdrvChildRole.inherit_options
block: Fix write flags in bdrv_backing_options
block: Use the actual current_flags during reopen
iotests: Add regression test for commit base locking
