net/rose: Use GFP_ATOMIC
The other calls to kmalloc in the same function use GFP_ATOMIC, and indeed two locks are held within the body of the function. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier f; @@ *f(...,GFP_ATOMIC,...) ... when != spin_unlock(...) when != read_unlock(...) when != write_unlock(...) when != read_unlock_irq(...) when != write_unlock_irq(...) when != read_unlock_irqrestore(...) when != write_unlock_irqrestore(...) when != spin_unlock_irq(...) when != spin_unlock_irqrestore(...) *f(...,GFP_KERNEL,...) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S. Miller <davem@davemloft.net>
