From: Nikolay Borisov Date: Wed, 7 Feb 2018 15:55:46 +0000 (+0200) Subject: btrfs: Remove root argument of cleanup_transaction X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=97cb39bb912c8092c5570578f2eb1b2988ac1af8;p=openwrt%2Fstaging%2Fblogic.git btrfs: Remove root argument of cleanup_transaction The only thing the passed root is used for is: 1. get a reference to the fs_info and to 2. call trace_btrfs_transaction_commit. We can achieve 1) by simply referring to the fs_info from passed trans object. As far as 2) is concerned cleanup_transaction is called from only one place and the 'root' argument passed is the one from the trans handle. No functional changes.
