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@gmail.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. fs/btrfs/transaction.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-)
