Bug Description
Thi bugfix has been included in the update of Lucid to 2.6.32.13 upstream stable (see Bug #583414).
----
I have already reported this upstream. on ext4, fiemap will not report extents if the requested logical region of a file overlaps the extent less than blocksize. So, if you request star=0, len=100, you will get nothing.
I can provide example code, if you need.
There is a patch attached to this bug report.
