drbd: introduce WRITE_SAME support

2016-06-14T03:43:07+00:00

We will support WRITE_SAME, if
 * all peers support WRITE_SAME (both in kernel and DRBD version),
 * all peer devices support WRITE_SAME
 * logical_block_size is identical on all peers.

We may at some point introduce a fallback on the receiving side
for devices/kernels that do not support WRITE_SAME,
by open-coding a submit loop. But not yet.

drbd: De-inline drbd_should_do_remote() and drbd_should_send_out_of_sync()

2015-11-25T16:22:00+00:00

There is no need to have these two as inline functions.  In addition,
drbd_should_send_out_of_sync() is only used in a single place, anyway.

drbd: prepare sending side for REQ_DISCARD

2014-04-30T19:46:55+00:00

Note that I do NOT call __drbd_chk_io_error for failed REQ_DISCARD.
That may be wrong, though, or needs to differ between EOPNOTSUPP and
other errors...

drbd: Create a dedicated struct drbd_device_work

2014-02-17T15:50:39+00:00

drbd_device_work is a work item that has a reference to a device,
while drbd_work is a more generic work item that does not carry
a reference to a device.

All callbacks get a pointer to a drbd_work instance, those callbacks
that expect a drbd_device_work use the container_of macro to get it.

drbd: Introduce "peer_device" object between "device" and "connection"

2014-02-17T15:44:51+00:00

In a setup where a device (aka volume) can replicate to multiple peers and one
connection can be shared between multiple devices, we need separate objects to
represent devices on peer nodes and network connections.

As a first step to introduce multiple connections per device, give each
drbd_device object a single drbd_peer_device object which connects it to a
drbd_connection object.
