This patchset fixes some races that I noticed when looked over the kdbd_printf() code. v2 is based on the feedback from Daniel Thompson and Sergey Senozhatsky. Changes agaist v1: + Completely remove kdb_event (Daniel) + Avoid using smp_processor_id() (Sergey) + Better describe the whole situation in 3rd patch (Daniel) Petr Mladek (3): kdb: Remove unused kdb_event handling kdb: Properly synchronize vkdb_printf() calls with other CPUs kdb: Call vkdb_printf() from vprintk_default() only when wanted include/linux/kdb.h | 2 +- kernel/debug/kdb/kdb_io.c | 37 +++++++++++++------------------------ kernel/debug/kdb/kdb_main.c | 1 - kernel/debug/kdb/kdb_private.h | 1 - kernel/printk/printk.c | 3 ++- 5 files changed, 16 insertions(+), 28 deletions(-) -- 1.8.5.6
