Lockdep works, based on the following: (1) Classifying locks properly (2) Checking relationship between the classes
If (1) is not good or (2) is not good, then we might get false positives. For (1), we don't have to classify locks 100% properly but need as enough as lockdep works. For (2), we should have a mechanism w/o logical defects. Cross-release added an additional capacity to (2) and requires (1) to get more precisely classified. Since the current classification level is too low for cross-release to work, false positives are being reported frequently with enabling cross-release. Yes. It's a obvious problem. It needs to be off by default until the classification is done by the level that cross-release requires. But, the logic (2) is valid and logically true. Please keep the code, mechanism, and logic. -- Thanks, Byungchul
