Currently only valid nextstate states are down and resume/idle so the
node shouldn't be in a drain state after transitioning into either of
these states.

(i.e. gres=gpu/tesla) it would get a count of 0.

Note that pipe2() is Linux-specific, but this whole cgroup plugin is
already Linux-specific in design, and the eventfd() call itself is
Linux-specific as well.

Only split nodes here if a node_features plugin is in use.

Otherwise node fragmentation will occur if the node config has
CPUs specified but not CoresPerSocket and Sockets.

This could be avoided by filling out the node definition, but
adding this workaround for backwards compatiblity.

Bug 5481.

There are subtle issues involved in treating a TCP transmission
as a unidirectional message delivery layer.

The original code path looks like: connect(), write(), close().
But Linux handles the write() and close() asynchronously behind the
scenes, and does not block until that write() has been ACK'd by the
remote end. So the write() and close() may succeed, even with data
still in flight. A communication error - and message loss - would
have been silently ignored, leading to unreliable message transmission.

Worse yet, one side of the connection would believe it sent the message,
while the receive side swears it never saw the packets. This leads to
infrequent and yet seemingly impossible data loss, and a very tough
bug to chase down.

This teardown code tries to force the connection to shut down in an
orderly manner, giving Slurm a chance to catch a connection problem
and the upstream calling path an opportunity to retransmit.

This teardown code is based on an approach described in Section 7.5
of "UNIX Network Programming" Volume 1 (Third Edition), specifically
the subsection regarding SO_LINGER. (And also covers why SO_LINGER is
not sufficent to prevent this issue.)

Bug 5164.

Previously only a single task of a job array could preempt during
backfill scheduling. This allows multiple tasks to preempt and have
resources reserved in backfill.
