From 834c7360f92ad88155c5628eb10d60419ebaa0df Mon Sep 17 00:00:00 2001 From: Jann Horn Date: Fri, 18 Oct 2019 17:39:46 +0200 Subject: binder: Remove incorrect comment about vm_insert_page() behavior vm_insert_page() does increment the page refcount, and just to be sure, I've confirmed it by printing page_count(page[0].page_ptr) before and after vm_insert_page(). It's 1 before, 2 afterwards, as expected.
