Subject: btrfs: memset cur_trans->delayed_refs to zero
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a099d0fdb34f00cee346703036a0a90d267e77d7;p=linux-beck.git

btrfs: memset cur_trans->delayed_refs to zero

Use memset() to null out the btrfs_delayed_ref_root of
btrfs_transaction instead of setting all the members to 0 by hand.
