From: Nikolay Borisov Date: Fri, 18 Aug 2017 14:58:23 +0000 (+0300) Subject: btrfs: remove superfluous chunk_tree argument from btrfs_alloc_dev_extent X-Git-Tag: v4.14-rc3~14^2~19 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b5d9071c4f5c087614eb477bff04795e325bea70;p=platform%2Fkernel%2Flinux-rpi3.git btrfs: remove superfluous chunk_tree argument from btrfs_alloc_dev_extent Currently this function is always called with the object id of the root key of the chunk_tree, which is always BTRFS_CHUNK_TREE_OBJECTID. So let's subsume it straight into the function itself. No functional change.
