tools/liblockdep: Use realpath for srctree and objtree

2014-02-27T02:22:01+00:00

If BUILD_SRC or CURDIR contains tailing '/', the file names passed to gcc will
contain '//'. It will be contained .o's in debuginfo, then confuse debugedit:

https://bugzilla.redhat.com/show_bug.cgi?id=304121

This patch uses realpath command to makesure potential tailing '/'s are removed.

tools/liblockdep: Add include directory to allow tests to compile

2014-02-27T02:21:56+00:00

All of the programs in the tests directory require the
liblockdep/mutex.h header in order to compile. Add the include directory
to the compiler options so that the tests can be built with the provided
Makefile.

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.

liblockdep: Add the 'lockdep' user-space utility

2013-11-27T10:56:25+00:00

This is a simple wrapper to make using liblockdep on existing
applications much easier.

After running 'make && make install', it becomes quite simple to
test things with liblockdep. For example, to try it on perf:

	lockdep perf

No other integration required.

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!
