Revision 4e101b0e6aa885f5786a058eefc1ce4b7cc7c44e authored by Akinobu Mita on 01 November 2011, 00:12:29 UTC, committed by Linus Torvalds on 01 November 2011, 00:30:56 UTC
When SPIN_BUG_ON is triggered, the lock owner information is reported. But it is omitted when spinlock lockup is detected. This information is useful especially on the architectures which don't implement trigger_all_cpu_backtrace() that is called just after detecting lockup. So report it and also avoid message format duplication.
