2021-01-14locking/lockdep: Mark local_lock_tPeter Zijlstra1-4/+14
The local_lock_t's are special, because they cannot form IRQ inversions, make sure we can tell them apart from the rest of the locks. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>
2020-10-09lockdep: Fix usage_traceoverflowPeter Zijlstra1-2/+6
Basically print_lock_class_header()'s for loop is out of sync with the the size of of ->usage_traces[]. Also clean things up a bit while at it, to avoid such mishaps in the future.

2020-07-17lockdep: Move list.h inclusion into lockdep.hHerbert Xu1-2/+0
Currently lockdep_types.h includes list.h without actually using any of its macros or functions. All it needs are the type definitions which were moved into types.h long ago. This potentially causes inclusion loops because both are included by many core header files. This patch moves the list.h inclusion into lockdep.h. Note that we could probably remove it completely but that could potentially result in compile failures should any end users not include list.h directly and also be unlucky enough to not get list.h via some other header file.

2020-06-17lockdep: Split header file into lockdep and lockdep_typesHerbert Xu1-0/+196
There is a header file inclusion loop between asm-generic/bug.h and linux/kernel.h. This causes potential compile failurs depending on the which file is included first. One way of breaking this loop is to stop spinlock_types.h from including lockdep.h. This patch splits lockdep.h into two files for this purpose.
