2016-02-29tools/lib/lockdep: Add userspace version of READ_ONCE()Alfredo Alvarez Fernandez1-0/+1
This was added to the kernel code in <1658d35ead5d> ("list: Use READ_ONCE() when testing for empty lists"). There's nothing special we need to do about it in userspace.

2015-11-06tools/liblockdep: explicitly declare lockdep API we call from liblockdepSasha Levin1-1/+2
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 <[email protected]>
2015-11-06tools/liblockdep: add userspace versions of WRITE_ONCE and RCU_INIT_POINTERSasha Levin1-0/+2
These were added to the kernel code in cee34d88c ("lockdep: Fix a race between /proc/lock_stat and module unload"). There's nothing special we need to do about them in userspace. Signed-off-by: Sasha Levin <[email protected]>
2015-08-25tools/liblockdep: Use the rbtree header provided by common tools headersSasha Levin1-1/+0
Recent changes to rbtree.h may break compilation. There is no reason to use a liblockdep specific header to begin with, so we'll use the one shared with all other tools/.

2015-08-25tools/liblockdep: Correct macro for WARNSasha Levin1-1/+1
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.

2015-05-13tools/liblockdep: Fix compilation errorEunbong Song1-0/+3
Recent changes to kernel/locking/lockdep.c broke the liblockdep build. Fix that. Signed-off-by: Eunbong Song <[email protected]> Signed-off-by: Sasha Levin <[email protected]>
2014-05-01tools: Consolidate types.hBorislav Petkov1-58/+0
Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

2014-05-01tools: Unify export.hBorislav Petkov1-7/+0
So tools/ has been growing three, at a different stage of their development export.h headers and so we should unite into one. Add tools/include/ to the include path of virtio and liblockdep to pick the shared header now.

2014-04-01tools/liblockdep: Ignore asmlinkage and visibleSasha Levin1-0/+3
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. Reported-by: Eunbong Song <[email protected]> Reported-by: Robin Hack <[email protected]> Signed-off-by: Sasha Levin <[email protected]>
2014-02-26tools/liblockdep: Add a stub for new rcu_is_watchingSasha Levin1-0/+5
Stub out rcu_is_watching(), prevents build error with the updated tree. Signed-off-by: Sasha Levin <[email protected]>
2014-02-26tools/liblockdep: Fix include of asm/hash.hIra W. Snyder1-0/+6
Commit 71ae8aac ("lib: introduce arch optimized hash library") added an include to <linux/hash.h> for setting up an architecture specific fast hash. This patch mirrors the fix used for perf, titled "tools: perf: util: fix include for non x86 architectures". Signed-off-by: Ira W.

2013-11-27liblockdep: Wrap kernel/locking/lockdep.c to allow usage from userspaceSasha Levin34-0/+431
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!
