[lustre-devel] [PATCH SERIES 5: 00/16] staging: lustre: use standard wait_event macros

[NeilBrown]

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
and got the conversion correct, but I've quite possibly messed up.
If you only review one series, this is the one that demands review.

I haven't converted the single use of l_wait_event_exclusive_head().
That needs more thought.

This is the last series for today.  I do have some more patches, but
that are all individual patches that I hope to send as a  set of
ad-hoc patches tomorrow.

Thanks,
NeilBrown
