However node is defined as an unsigned int. So it cannot be negative. Therefore remove the check as it will always be true. Signed-off-by: Julien Grall Signed-off-by: Julien Grall Acked-by: Andrew Cooper Acked-by: Jan Beulich --- I have looked at the history. AFAICT, node has always be defined as unsigned int. So the ASSERT() may have never been useful (?). --- xen/common/page_alloc.c | 1 - 1 file changed, 1 deletion(-) diff --git a/xen/common/page_alloc.c b/xen/common/page_alloc.c index 46357182375a..e971bf91e0be 100644 --- a/xen/common/page_alloc.c +++ b/xen/common/page_alloc.c @@ -1441,7 +1441,6 @@ static void free_heap_pages( unsigned int zone = page_to_zone(pg); ASSERT(order <= MAX_ORDER); - ASSERT(node >= 0); spin_lock(&heap_lock);
