From 262c96a3c3670bf2322b9a0c9d74e2a3d9e43be0 Mon Sep 17 00:00:00 2001 From: Anand Jain Date: Fri, 1 Mar 2019 12:34:50 +0800 Subject: btrfs: refactor btrfs_set_prop and add btrfs_set_prop_trans btrfs_set_prop() takes transaction pointer as the first argument, however in ioctl.c for the purpose of setting the compression property, we call btrfs_set_prop() with NULL transaction pointer. Down in the call chain btrfs_setxattr() starts transaction to update the attribute and also to update the inode. So for clarity, create btrfs_set_prop_trans() with no transaction pointer as argument, in preparation to start transaction here instead of doing it down the call chain at btrfs_setxattr(). Also now the btrfs_set_prop() is a static function.
