drbd: Introduce protocol version 100 headers · 0c8e36d9

由 Andreas Gruenbacher 提交于 3月 30, 2011

The 8 byte header finally becomes too small. With the protocol 100 header we
have 16 bit for the volume number, proper 32 bit for the data length, and
32 bit for further extensions in the future.

Previous versions of drbd are using version 80 headers for all packets
short enough for protocol 80.  They support both header versions in
worker context, but only version 80 headers in asynchronous context.
For backwards compatibility, continue to use version 80 headers for
short packets before protocol version 100.

From protocol version 100 on, use the same header version for all
packets.

drbd: Replace and remove old primitives · 9f5bdc33

由 Andreas Gruenbacher 提交于 3月 28, 2011

Centralize sock->mutex locking and unlocking in [drbd|conn]_prepare_command()
and [drbd|conn]_send_comman().

Therefore all *_send_* functions are touched to use these primitives instead
of drbd_get_data_sock()/drbd_put_data_sock() and former helper functions.

That change makes the *_send_* functions more standardized.
