Subject: [PATCH 0/9] Lock ordering documentation and annotation for lockdep
Date: Fri, 13 Mar 2020 18:46:52 +0100 [thread overview]
Message-ID: <20200313174701.148376-1-bigeasy@linutronix.de> (raw)
The first patch introduces the long asked locking documentation
regarding spinlock_t vs raw_spinlock_t (and other locking primitives).
Followed by updates to obey the rules including a change to completions
to use struct swait_queue_head instead of wait_queue_head_t.
It ends with lockdep updates to recognize the "bad" lock nesting. This
new lockdep feature is activated by CONFIG_PROVE_RAW_LOCK_NESTING. Once
enabled it will report for instance printk, the memory allocator or the
workqueue implementation. This is known and it is worked on.
