> The refactoring in HDFS-2003 allowed findbugs to expose two potential bugs:
> - the atime field logged with OP_MKDIR is unused
> - the timestamp field logged with OP_CONCAT_DELETE is unused
> The concat issue is definitely real. The atime for MKDIR might always be identical to
mtime in that case, in which case it could be ignored.
