Subject: urcu-wait: Fix wait state load/store
X-Git-Url: https://git.liburcu.org/?a=commitdiff_plain;h=2ea38794876c907639971035ed29c4e59964fd7f;hp=2ea38794876c907639971035ed29c4e59964fd7f;p=urcu.git

urcu-wait: Fix wait state load/store

The state of a wait node must be accessed atomically. Also, the action
of busy loading until the teardown state is seen must follow a
CMM_ACQUIRE semantic while storing the teardown must follow a
CMM_RELEASE semantic.
