[PATCH 01/21] liblockdep: Fix undefined symbol prandom_u32

[Levin, Alexander (Sasha Levin)]

From: Ben Hutchings <ben@decadent.org.uk>

__lock_pin_lock() now calls prandom_u32() which is not defined in
liblockdep.  __lock_pin_lock() and its caller lock_pin_lock() are dead
code in liblockdep, but we still need to provide a definition of
prandom_u32() in case lazy binding is disabled.

liblockdep was essentially build-broken for almost a year.

I worry about and question liblockdep's general maintainability and as a 
maintainer of lockdep I can see only two options going forward: either it's 
cleaned up for good (going beyond what is needed to fix the build failures and 
warnings), or we remove it (with the option of reintroducing it if/when it's clean 
enough).

I.e. the quality bar has increased.

No, if it does not improve then I'd rather remove it, and re-add it at a later 
date if/when it's clean enough.

What does the build breakage has to do with converting the way we
use headers? There's no broken functionality as far as I can tell,
so why is the header thing defined as a "fix" to begin with?

I also don't see a single tools/ project to exclusively use tools/include
at this point.

Would you rather keep liblockdep broken for the next couple of months
until this is sorted? I really doubt I could get something (+ enough
time to soak in -next) for v4.13, so we're looking at v4.14 at the
earliest.

Since liblockdep was broken for an extended period of time I'd really
like to see this fixed before I apply any more patches.

Thanks,

Right, and as you can see from this patchset where we added to
tools/include/ when needed and removed from lib/lockdep/uinclude,
liblockdep is slowly creeping the "right" way.

perf, like liblockdep, didn't finish the switch to exclusively use
tools/include/ yet.

I can put more work into getting it done over the next few releases,
but it's not something I see as a critical fix for the upcoming
release.

Yeah, so what needs to be fixed as well is for liblockdep to exclusively use 
tools/include/ (and extend those headers where required).

perf already uses that method and it works well.

liblockdep already uses tools/include/ in part, but even after I apply all your 
patches, there's still lib/lockdep/uinclude/ which appears to duplicate a number 
of headers.

I did a quick check - for example WARN_ON() et al is duplicated in 
tools/lib/lockdep/uinclude/linux/kernel.h.

Thanks,
