Subject: [PATCH 00/30] staging: lustre: tidy up - module init and includes
This series addresses two particular issues, and includes a bunch
of related tidy-ups as well.
1/ there were a few reports of lustre crashing because a char-special
couldn't be registered. We fixed the char-special registration so it
won't fail, but the crash it still bad.
The root cause is that most modules assume libcfs has initialised
properly without checking that it did. When separate modules are
used, there is no need to check. When all is compiled into the
kernel, the need does arise.
So this series fixes that and also makes sure no module registers any
service unless it initializes properly.
2/ As James Simmons recently noted, dumping all the extra headers
from linux/libcfs.h into libcfs.h isn't a suitable end-game.
This series completes the work started at that time by removing
all the includes from libcfs.h. I did this over a series of patches
as it was easier to work that way. They don't really need much review,
just compile testing which I have done (both with and without
modules, and with and without SMP).
There is also come other cleaning up of include file content in there.
Sorry the series is so long, but most of it should be easy to review.
Thanks,
NeilBrown
