This function was used to broadcast the (leading part of the)
bio payload in case we see a data integrity error. It could be received
from userland with the drbdsetup events subcommand,
to have a peek into the payload that caused the checksum mismatch,
and guess from there what may have caused the mismatch,
mainly to guess wether it was modification of in-flight data,
or data corruption by broken hardware or software bugs.
Meanwhile we support bios that are larger than the maximum payload a
netlink datagram can carry.
And we have means to reliably detect modification of in-flight data by
calculating, and comparing, the checksum before and after sendmsg.
There is no need to carry this around anymore.

drbd: Improve how conflicting writes are handled
The previous algorithm for dealing with overlapping concurrent writes
was generating unnecessary warnings for scenarios which could be
legitimate, and did not always handle partially overlapping requests
correctly. Improve it algorithm as follows:
* While local or remote write requests are in progress, conflicting new
local write requests will be delayed (commit
82172f7).
* When a conflict between a local and remote write request is detected,
the node with the discard flag decides how to resolve the conflict: It
will ask its peer to discard conflicting requests which are fully
contained in the local request and retry requests which overlap only
partially. This involves a protocol change.

Commit
9b1e63e changed the concurrent write detection algorithm to only insert
peer requests into write_requests tree after determining that there is no
conflict. With this change, new conflicting local requests could be added
while the algorithm runs, but this case was not handled correctly. Instead of
making the algorithm deal with this case, switch back to adding peer requests
to the write_requests tree immediately: this improves fairness.
