From a0357511f29f9b83e2c0d12621c339a5900eaa5a Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Mon, 21 Aug 2017 12:43:44 +0300 Subject: [PATCH] btrfs: Remove unused parameters from various functions iterate_dir_item:found_key - introduced in 31db9f7c23fb ("Btrfs: introduce BTRFS_IOC_SEND for btrfs send/receive"), yet never used. record_ref:num - ditto This is a first pass with the low-hanging fruit. There are still quite a few unsued parameters in some function which have to abide by a callback interface.
