drbd: fix race between deconfiguring and reconfiguring network If a drbd_nl_net_conf hits the small window between the state change to C_STANDALONE and the corresponding cleanup in after_state_ch, that cleanup would throw away stuff we now need again, and later trigger BUG_ON()s. Fixed by properly serializing the new config request with any pending cleanup. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
