Issue #3094 has been updated by dillon. Status changed from New to Closed
It's actually correct, just badly organized code. The first condition has to be rechecked after the page is busied. I'll rewrite it later this week to make it more obvious. -Matt ---------------------------------------- Bug #3094: dragonfly/sys/vm/vm_page.c:1389: bed sequence of if statements ? http://bugs.dragonflybsd.org/issues/3094#change-13294 * Author: dcb * Status: Closed * Priority: Normal * Assignee: * Category: Kernel * Target version: ---------------------------------------- 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; -- You have received this notification because you have either subscribed to it, or are involved in it.
