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.

tools/liblockdep: Correct macro for WARN

2015-08-25T07:44:22+00:00

As Peter Zijlstra pointed out, the varargs for WARN() are optional, so we need to correctly handle the case where they don't exist. This would cause a compilation error.

tools/liblockdep: Fix compilation error

2015-05-13T10:12:20+00:00

Recent changes to kernel/locking/lockdep.c broke the liblockdep build. Fix that. Signed-off-by: Eunbong Song Signed-off-by: Sasha Levin

liblockdep: Wrap kernel/locking/lockdep.c to allow usage from userspace

2013-11-27T10:55:21+00:00

kernel/locking/lockdep.c deals with validating locking scenarios for various architectures supported by the kernel. There isn't anything kernel specific going on in lockdep, and when we compare userspace to other architectures that don't have to deal with irqs such as s390, they become all too similar. We wrap kernel/locking/lockdep.c and include/linux/lockdep.h with several headers which allow us to build and use lockdep from userspace. We don't touch the kernel code itself which means that any work done on lockdep in the kernel will automatically benefit userspace lockdep as well!
