Subject: [PATCH] xfs: return FIEMAP_EXTENT_UNKNOWN for delayed allocation extent
Date: Thu, 6 Jun 2013 06:24:01 -0700 (PDT)	[thread overview]
Message-ID: <51B08D71.7090404@oracle.com> (raw)

From: Jie Liu <jeff.liu@oracle.com>

For FIEMAP ioctl(2), if an extent is in delayed allocation
state, we need to return the FIEMAP_EXTENT_UNKNOWN flag except
the FIEMAP_EXTENT_DELALLOC because its data location is unknown.
