| |
This patch adds __FILE__ and __LINE__ to lockdep_map of rw_semaphore. This patch only affects to x86 architecture dependent rwsem.
If this patch is accepted, I'll prepare and send the patch adds __FILE__ and __LINE__ to rw_semaphore of other architectures which provides architecture dependent rwsem.h .
