tools/lib/lockdep: Don't mix fd-based and stream IO

2017-06-05T07:28:08+00:00

Mixing fd-based and stream-base IO results in interleaved output like
following:

=====================================

conopal/372 is trying to release lock (0x3a45c) at:
/lib/libpt.so.2.17-alpha2(_ZN11PTimedMutex6SignalEv+0x3c) [0xb613c688]
but there are no more locks to release!
other info that might help us debug this:
no locks held by conopal/372.

tools/lib/lockdep: Fix 'defined but not used' warning for init_utsname()

2017-06-05T07:28:06+00:00

We define init_utsname() as static but not inline, resulting
in a warning for every source file that includes lockdep.h but
doesn't call it.

Since it is only used by lockdep.c, define it in there.

tools/lib/lockdep: Fix 'set but not used' warnings

2017-06-05T07:28:06+00:00

liblockdep defines trivial macros for working with interrupt flags, as
interrupts are never disabled in userland.  This results in warnings
from gcc when -Wunused-but-set-variable is enabled, and it is enabled
by -Wall.  Fix this by evaluating the flags parameter and casting it to
void.

tools/lib/lockdep: Fix 'unused value' warnings

2017-06-05T07:28:05+00:00

liblockdep defines various macros that may expand to an expression
with no effect, while the in-kernel definition does have an effect.
This results in warnings from gcc when -Wunused-value is enabled, and
is is enabled by -Wall.  Fix this by introducing trivial functions,
as function return values are generally allowed to be ignored.
