From: Julia Lawall <ju...@diku.dk> The containing function is called from several places. At one of them, in the function __sigp_stop, the spin lock &fi->lock is held.
The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @gfp exists@ identifier fn; position p; @@ fn(...) { ... when != spin_unlock when any gfp_ker...@p ... when any } @locked@ identifier gfp.fn; @@ spin_lock(...) ... when != spin_unlock fn(...) @depends on locked@ position gfp.p; @@ - gfp_ker...@p + GFP_ATOMIC // </smpl> Signed-off-by: Julia Lawall <ju...@diku.dk> --- arch/s390/kvm/sigp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -u -p a/arch/s390/kvm/sigp.c b/arch/s390/kvm/sigp.c --- a/arch/s390/kvm/sigp.c +++ b/arch/s390/kvm/sigp.c @@ -113,7 +113,7 @@ static int __inject_sigp_stop(struct kvm { struct kvm_s390_interrupt_info *inti; - inti = kzalloc(sizeof(*inti), GFP_KERNEL); + inti = kzalloc(sizeof(*inti), GFP_ATOMIC); if (!inti) return -ENOMEM; inti->type = KVM_S390_SIGP_STOP; -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
