Generate the state bit definitions from the lockdep_states.h file. Also, move LOCK_USED to last, so that the USED_IN USED_IN_READ ENABLED ENABLED_READ states are nicely bit aligned -- we're going to use that property Signed-off-by: Peter Zijlstra --- kernel/lockdep_internals.h | 47 +++++++++++++++++++-------------------------- 1 file changed, 20 insertions(+), 27 deletions(-) Index: linux-2.6/kernel/lockdep_internals.h =================================================================== --- linux-2.6.orig/kernel/lockdep_internals.h +++ linux-2.6/kernel/lockdep_internals.h @@ -10,43 +10,36 @@ * Lock-class usage-state bits: */ enum lock_usage_bit { - LOCK_USED = 0, - LOCK_USED_IN_HARDIRQ, - LOCK_USED_IN_SOFTIRQ, - LOCK_USED_IN_RECLAIM_FS, - LOCK_ENABLED_SOFTIRQ, - LOCK_ENABLED_HARDIRQ, - LOCK_ENABLED_RECLAIM_FS, - LOCK_USED_IN_HARDIRQ_READ, - LOCK_USED_IN_SOFTIRQ_READ, - LOCK_USED_IN_RECLAIM_FS_READ, - LOCK_ENABLED_SOFTIRQ_READ, - LOCK_ENABLED_HARDIRQ_READ, - LOCK_ENABLED_RECLAIM_FS_READ, +#define LOCKDEP_STATE(__STATE) \ + LOCK_USED_IN_##__STATE, \ + LOCK_USED_IN_##__STATE##_READ, \ + LOCK_ENABLED_##__STATE, \ + LOCK_ENABLED_##__STATE##_READ, +#include "lockdep_states.h" +#undef LOCKDEP_STATE + LOCK_USED, LOCK_USAGE_STATES }; /* * Usage-state bitmasks: */ -#define LOCKF_USED (1 << LOCK_USED) -#define LOCKF_USED_IN_HARDIRQ (1 << LOCK_USED_IN_HARDIRQ) -#define LOCKF_USED_IN_SOFTIRQ (1 << LOCK_USED_IN_SOFTIRQ) -#define LOCKF_USED_IN_RECLAIM_FS (1 << LOCK_USED_IN_RECLAIM_FS) -#define LOCKF_ENABLED_HARDIRQ (1 << LOCK_ENABLED_HARDIRQ) -#define LOCKF_ENABLED_SOFTIRQ (1 << LOCK_ENABLED_SOFTIRQ) -#define LOCKF_ENABLED_RECLAIM_FS (1 << LOCK_ENABLED_RECLAIM_FS) +#define __LOCKF(__STATE) LOCKF_##__STATE = (1 << LOCK_##__STATE), + +enum { +#define LOCKDEP_STATE(__STATE) \ + __LOCKF(USED_IN_##__STATE) \ + __LOCKF(USED_IN_##__STATE##_READ) \ + __LOCKF(ENABLED_##__STATE) \ + __LOCKF(ENABLED_##__STATE##_READ) +#include "lockdep_states.h" +#undef LOCKDEP_STATE + __LOCKF(USED) +}; #define LOCKF_ENABLED_IRQ (LOCKF_ENABLED_HARDIRQ | LOCKF_ENABLED_SOFTIRQ) #define LOCKF_USED_IN_IRQ (LOCKF_USED_IN_HARDIRQ | LOCKF_USED_IN_SOFTIRQ) -#define LOCKF_USED_IN_HARDIRQ_READ (1 << LOCK_USED_IN_HARDIRQ_READ) -#define LOCKF_USED_IN_SOFTIRQ_READ (1 << LOCK_USED_IN_SOFTIRQ_READ) -#define LOCKF_USED_IN_RECLAIM_FS_READ (1 << LOCK_USED_IN_RECLAIM_FS_READ) -#define LOCKF_ENABLED_HARDIRQ_READ (1 << LOCK_ENABLED_HARDIRQ_READ) -#define LOCKF_ENABLED_SOFTIRQ_READ (1 << LOCK_ENABLED_SOFTIRQ_READ) -#define LOCKF_ENABLED_RECLAIM_FS_READ (1 << LOCK_ENABLED_RECLAIM_FS_READ) - #define LOCKF_ENABLED_IRQ_READ \ (LOCKF_ENABLED_HARDIRQ_READ | LOCKF_ENABLED_SOFTIRQ_READ) #define LOCKF_USED_IN_IRQ_READ \ -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
