[PATCH] lockdep: locking API self tests Introduce DEBUG_LOCKING_API_SELFTESTS, which uses the generic lock debugging code's silent-failure feature to run a matrix of testcases. There are 210 testcases currently: +----------------------- \| Locking API testsuite: +------------------------------+------+------+------+------+------+------+ \| spin \|wlock \|rlock \|mutex \| wsem \| rsem \| -------------------------------+------+------+------+------+------+------+ A-A deadlock: ok \| ok \| ok \| ok \| ok \| ok \| A-B-B-A deadlock: ok \| ok \| ok \| ok \| ok \| ok \| A-B-B-C-C-A deadlock: ok \| ok \| ok \| ok \| ok \| ok \| A-B-C-A-B-C deadlock: ok \| ok \| ok \| ok \| ok \| ok \| A-B-B-C-C-D-D-A deadlock: ok \| ok \| ok \| ok \| ok \| ok \| A-B-C-D-B-D-D-A deadlock: ok \| ok \| ok \| ok \| ok \| ok \| A-B-C-D-B-C-D-A deadlock: ok \| ok \| ok \| ok \| ok \| ok \| double unlock: ok \| ok \| ok \| ok \| ok \| ok \| bad unlock order: ok \| ok \| ok \| ok \| ok \| ok \| --------------------------------------+------+------+------+------+------+ recursive read-lock: \| ok \| \| ok \| --------------------------------------+------+------+------+------+------+ non-nested unlock: ok \| ok \| ok \| ok \| --------------------------------------+------+------+------+ hard-irqs-on + irq-safe-A/12: ok \| ok \| ok \| soft-irqs-on + irq-safe-A/12: ok \| ok \| ok \| hard-irqs-on + irq-safe-A/21: ok \| ok \| ok \| soft-irqs-on + irq-safe-A/21: ok \| ok \| ok \| sirq-safe-A => hirqs-on/12: ok \| ok \| ok \| sirq-safe-A => hirqs-on/21: ok \| ok \| ok \| hard-safe-A + irqs-on/12: ok \| ok \| ok \| soft-safe-A + irqs-on/12: ok \| ok \| ok \| hard-safe-A + irqs-on/21: ok \| ok \| ok \| soft-safe-A + irqs-on/21: ok \| ok \| ok \| hard-safe-A + unsafe-B #1/123: ok \| ok \| ok \| soft-safe-A + unsafe-B #1/123: ok \| ok \| ok \| hard-safe-A + unsafe-B #1/132: ok \| ok \| ok \| soft-safe-A + unsafe-B #1/132: ok \| ok \| ok \| hard-safe-A + unsafe-B #1/213: ok \| ok \| ok \| soft-safe-A + unsafe-B #1/213: ok \| ok \| ok \| hard-safe-A + unsafe-B #1/231: ok \| ok \| ok \| soft-safe-A + unsafe-B #1/231: ok \| ok \| ok \| hard-safe-A + unsafe-B #1/312: ok \| ok \| ok \| soft-safe-A + unsafe-B #1/312: ok \| ok \| ok \| hard-safe-A + unsafe-B #1/321: ok \| ok \| ok \| soft-safe-A + unsafe-B #1/321: ok \| ok \| ok \| hard-safe-A + unsafe-B #2/123: ok \| ok \| ok \| soft-safe-A + unsafe-B #2/123: ok \| ok \| ok \| hard-safe-A + unsafe-B #2/132: ok \| ok \| ok \| soft-safe-A + unsafe-B #2/132: ok \| ok \| ok \| hard-safe-A + unsafe-B #2/213: ok \| ok \| ok \| soft-safe-A + unsafe-B #2/213: ok \| ok \| ok \| hard-safe-A + unsafe-B #2/231: ok \| ok \| ok \| soft-safe-A + unsafe-B #2/231: ok \| ok \| ok \| hard-safe-A + unsafe-B #2/312: ok \| ok \| ok \| soft-safe-A + unsafe-B #2/312: ok \| ok \| ok \| hard-safe-A + unsafe-B #2/321: ok \| ok \| ok \| soft-safe-A + unsafe-B #2/321: ok \| ok \| ok \| hard-irq lock-inversion/123: ok \| ok \| ok \| soft-irq lock-inversion/123: ok \| ok \| ok \| hard-irq lock-inversion/132: ok \| ok \| ok \| soft-irq lock-inversion/132: ok \| ok \| ok \| hard-irq lock-inversion/213: ok \| ok \| ok \| soft-irq lock-inversion/213: ok \| ok \| ok \| hard-irq lock-inversion/231: ok \| ok \| ok \| soft-irq lock-inversion/231: ok \| ok \| ok \| hard-irq lock-inversion/312: ok \| ok \| ok \| soft-irq lock-inversion/312: ok \| ok \| ok \| hard-irq lock-inversion/321: ok \| ok \| ok \| soft-irq lock-inversion/321: ok \| ok \| ok \| hard-irq read-recursion/123: ok \| soft-irq read-recursion/123: ok \| hard-irq read-recursion/132: ok \| soft-irq read-recursion/132: ok \| hard-irq read-recursion/213: ok \| soft-irq read-recursion/213: ok \| hard-irq read-recursion/231: ok \| soft-irq read-recursion/231: ok \| hard-irq read-recursion/312: ok \| soft-irq read-recursion/312: ok \| hard-irq read-recursion/321: ok \| soft-irq read-recursion/321: ok \| --------------------------------+-----+---------------- Good, all 210 testcases passed! \| --------------------------------+ Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 2006-07-03 07:24:48 +00:00			`#undef LOCK`
