WinDRBD 1.2.1 released

[Johannes Thoma]

Dear WinDRBD community,

I just released WinDRBD 1.2.1. The main difference to the 1.2.0 version
is that the workqueue implementation has been rewritten in order to
allow multi-threaded workqueues. This fixes a hang in Disconnecting
when resources are disconnected on different nodes in parallel. Also
the new workqueue implementation is based solely on (existing) Linux
primitives (threads, spinlocks, wait queues and lists) and could compile
and work (in theory, I haven't tested that) also in a recent Linux kernel.

Unless you are affected by resources hanging in Disconnected there
is no urgent need to upgrade.

Best regards,

- Johannes
