* tools/liblockdep: explicitly declare lockdep API we call from liblockdepSasha Levin2015-11-06
| | | | | | | It seems that newer gcc complains about lack of explicit declaration for some of the API we use, add it in. Signed-off-by: Sasha Levin <sasha.levin@oracle.com>
* tools/liblockdep: Ignore asmlinkage and visibleSasha Levin2014-04-01
| | | | | | | | | | | Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep. Since we don't need asmlinkage in liblockep, just ignore it.

* liblockdep: Wrap kernel/locking/lockdep.c to allow usage from userspaceSasha Levin2013-11-27
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!
