Ticketing spinlocks - How to get to the owner who locked the spinlock?

Hi All, Currently I am looking into an issue which is holding the printk lock(logbuf_lock) logbuf_lock = { raw_lock = { owner = 0, next = 4 } } I read about ticketing spinlocks to understand the above output. I understood that 4 cpu's are waiting for the lock while someone already has it. I would like to know who has it? Is there a way I can know which process is acquiring a given spinlock? Is the information not stored in it? I am using crash tool to analyse the dump Regards, Manty
