sched/debug: Add taint on "BUG: Sleeping function called from invalid context"
Seeing this, it occurs to me that we should probably add a taint here: BUG: sleeping function called from invalid context at mm/slab.h:388 in_atomic(): 0, irqs_disabled(): 0, pid: 32211, name: trinity-c3 Preemption disabled at:[<ffffffff811aaa37>] console_unlock+0x2f7/0x930 CPU: 3 PID: 32211 Comm: trinity-c3 Not tainted 4.7.0-rc7+ #19 ^^^^^^^^^^^ Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Ubuntu-1.8.2-1ubuntu1 04/01/2014 0000000000000000 ffff8800b8a17160 ffffffff81971441 ffff88011a3c4c80 ffff88011a3c4c80 ffff8800b8a17198 ffffffff81158067 0000000000000de6 ffff88011a3c4c80 ffffffff8390e07c 0000000000000184 0000000000000000 Call Trace: [...] BUG: sleeping function called from invalid context at arch/x86/mm/fault.c:1309 in_atomic(): 0, irqs_disabled(): 0, pid: 32211, name: trinity-c3 Preemption disabled at:[<ffffffff8119db33>] down_trylock+0x13/0x80 CPU: 3 PID: 32211 Comm: trinity-c3 Not tainted 4.7.0-rc7+ #19 ^^^^^^^^^^^ Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Ubuntu-1.8.2-1ubuntu1 04/01/2014 0000000000000000 ffff8800b8a17e08 ffffffff81971441 ffff88011a3c4c80 ffff88011a3c4c80 ffff8800b8a17e40 ffffffff81158067 0000000000000000 ffff88011a3c4c80 ffffffff83437b20 000000000000051d 0000000000000000 Call Trace: [...] Signed-off-by: Vegard Nossum <[email protected]> Acked-by: Thomas Gleixner <[email protected]> Cc: Andrew Morton <[email protected]> Cc: Linus Torvalds <[email protected]> Cc: Mike Galbraith <[email protected]> Cc: Paul E.
