Since unwind_frame_init_from_blocked_task() may be called from interrupt/in_atomic context, it needs to kmalloc() memory with GFP_ATOMIC instead of GFP_KERNEL. This fixes this warning (ShowTasks called from sysrq handler): BUG: sleeping function called from invalid context at mm/slab.c:3044 in_atomic(): 1, irqs_disabled(): 1, pid: 2119, name: miniruby Backtrace: [<10132e78>] __might_sleep+0x4c/0x118 [<1018f644>] kmem_cache_alloc+0x2c/0xb4 [<1011bae0>] unwind_frame_init_from_blocked_task+0x30/0xa0 [<1010fd3c>] parisc_show_stack+0x3c/0xac [<10132c7c>] show_state_filter+0x80/0xd8 [<102f4074>] __handle_sysrq+0xd0/0x1b0 [<102f9558>] receive_chars+0x22c/0x318 [<102f9940>] serial8250_handle_port+0x40/0x88 [<102f9a8c>] serial8250_interrupt+0x104/0x10c [<10161920>] handle_IRQ_event+0x44/0x94 [<10161acc>] __do_IRQ+0x15c/0x1dc [<102c442c>] superio_interrupt+0x74/0xa8 [<10161920>] handle_IRQ_event+0x44/0x94 [<10161acc>] __do_IRQ+0x15c/0x1dc [<10110fb4>] do_cpu_irq_mask+0x90/0xbc [<10114068>] intr_return+0x0/0x4 Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca> |
