From f993c883ad8e111fb9e9ae603540acbe94f7246c Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 20 Apr 2011 23:35:57 +0200 Subject: btrfs: drop unused argument from extent_io_tree_init all callers pass GFP_NOFS, but the GFP mask argument is not used in the function; GFP_ATOMIC is passed to radix tree initialization and it's the only correct one, since we're using the preload/insert mechanism of radix tree. Let's drop the gfp mask from btrfs function, this will not change behaviour.
