[lustre-devel] [PATCH 02/16] staging: lustre: replace simple cases of l_wait_event() with wait_event().

Sun Dec 17 23:17:59 PST 2017
When the lwi arg is full of zeros, l_wait_event() behaves almost
identically to the standard wait_event() interface, so use that
instead.
The only difference in behavior is that l_wait_event() blocks all
signals and uses an TASK_INTERRUPTIBLE wait, while wait_event()
does not block signals, but waits in state TASK_UNINTERRUPTIBLE.
This means that processes blocked in wait_event() will contribute
to the load average. This behavior is (arguably) more correct - in
most cases.
In some cases, the wait is in a service thread waiting for work to
do. In these case we should wait TASK_NOLOAD order with
TASK_UNINTERRUPTIBLE. To facilitate this, add a "wait_event_noload()"
macro. This should eventually be moved into include/linux/wait.h.
There is one case where wait_event_exclusive_noload() is needed.
So we add a macro for that too.
