Description

dragonfly/sys/vm/vm_page.c:1389]: (style) Expression is always false because 'else if' condition matches previous condition at line 1384.

Source code is

if (m->valid != VM_PAGE_BITS_ALL ||
            (m->flags & PG_FICTITIOUS)) {
            m = NULL;
        } else if (vm_page_sbusy_try(m)) {
            m = NULL;
        } else if (m->valid != VM_PAGE_BITS_ALL ||
               (m->flags & PG_FICTITIOUS)) {
            vm_page_sbusy_drop(m);
            m = NULL;
