the effect is to wait indefinitely for the event, polling
on the timeout in case we missed a wake_up.
If LWI_ON_SIGNAL_NOOP is given, then also abort (at the timeout)
if a "fatal" signal is pending.
Make this more obvious is both places "
This wait current wakes up every second to re-test if
imp_flight is zero. If we ensure wakeup is called whenever
imp_flight is decremented to zero, we can just have a simple
wait_event_timeout().
So add a wake_up_all to the one place it is missing, and simplify
the wait_event.

If a signal-callback (lwi_on_signal) is set without lwi_allow_intr, as
is the case in ldlm_completion_ast(), the behavior depends on the
timeout set.
If a timeout is set, then signals are ignored. If the timeout is
reached, the timeout handler is called.
If no timeout is set, then "fatal" signals
If l_wait_event() is given a function to be called on a signal,
but no timeout or timeout handler, then the intr function is simply
called at the end if the wait was aborted by a signal.
So a simpler way to write the code (in the one place this case is
used) it to open-code the body of the function
This use of l_wait_event() is a polling loop that re-checks
every second. Make this more obvious with a while loop
and wait_event_timeout().

We can replace l_wait_event() with
wait_event_noload_timeout() here providing we call the
timeout function when wait_event_timeout() returns zero.

Two places that LWI_TIMEOUT_INTERVAL() is used, the outcome is a
simple polling loop that polls every second for some event (with a
limit).
So write a simple loop to make this more apparent.

Rather an using l_wait_event(), use wait_event_timeout()
with an explicit loop so it is easier to see what is happening.

This is the last remaining use of l_wait_event().
It is the only use of LWI_TIMEOUT_INTR_ALL() which
has a meaning that timeouts can be interrupted.
Only interrupts by "fatal" signals are allowed, so
introduce l_wait_event_abortable_timeout() to
support this.

Lustre has l_wait_event() which is a complex macro that does
similar things to the wait_event macro family in Linux.
This patch series converts all l_wait_event to something more
familiar to Linux developers.
Some of the conversions are subtle. I think I've understood the code

Hello,
This series ensure the build-ids for target binary and debuginfo
are matched. If there is a mismatch, it warns user to check the
package versions.
To reproduce the problematic environment (on Fedora26),
I did following operations;

glibc-2.25-12.f
