tools/liblockdep: Account for bitfield changes in lockdeps lock_acquire

2014-07-07T16:20:16+00:00

Commit fb9edbe984 shortened held_lock->check from a 2-bit field to a 1-bit field. Make liblockdep compatible with the new definition by passing check=1 to lock_acquire() calls, rather than the old value check=2 (which inadvertently disabled checks by overflowing to 0). Without this fix, several of the test cases in liblockdep run_tests.sh were failing. Signed-off-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Remove debug print left over from development

2014-07-07T16:14:27+00:00

Remove a debug print in init_preload() which was left over from development and isn't usefull at all currently. It was also causing false positive test results. Reported-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Fix comparison of a boolean value with a value of 2

2014-07-07T16:02:21+00:00

Comparison of a boolean value (!__init_state) with a value of 2 (done) as currently happens in the code is unlikely to succeed and causes repeated initialization of the pthread function pointers. Instead, remove boolean comparison so that we would initialize said function pointers only once.

tools/liblockdep: Fix initialization code path

2014-02-27T02:21:49+00:00

This makes initialization actually happen. Without it, initialization is always skipped due to an incorrect conditional statement. Signed-off-by: Ira W. Snyder Signed-off-by: Sasha Levin

liblockdep: Support using LD_PRELOAD

2013-11-27T10:55:24+00:00

This allows lockdep to be used without being compiled in the original program. Usage is quite simple: LD_PRELOAD=/path/to/liblockdep.so /path/to/my/program And magically, you'll have lockdep checking in your program!
