Subject: [PATCH] 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.
Signed-off-by: Alexandru Moise <00moses.alexander00@...il.com>
---
Rather than setting each member of ->delayed_refs by hand we should
adhere to the practice of using memset() calls to fill those memory
locations with zeroes. We make an exception however for the rb_root
and atomic_t variable to make room for change in future delayed_refs
implementations.
