From fc4adbff823f76577ece26dcb88bf6f8392dbd43 Mon Sep 17 00:00:00 2001 From: Alex Gartrell Date: Tue, 20 May 2014 13:07:56 -0700 Subject: [PATCH] btrfs: Drop EXTENT_UPTODATE check in hole punching and direct locking In these instances, we are trying to determine if a page has been accessed since we began the operation for the sake of retry. This is easily accomplished by doing a gang lookup in the page mapping radix tree, and it saves us the dependency on the flag (so that we might eventually delete it). btrfs_page_exists_in_range borrows heavily from find_get_page, replacing the radix tree look up with a gang lookup of 1, so that we can find the next highest page >= index and see if it falls into our lock range.
