Description

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.
