[PATCH v2 0/2] Fiemap's range query

[Nikolay Borisov <nborisov@suse.com>]

So here is an implementation of fiemap's range query. The only major change 
apart from range support is that for files which consists of only a hole fiemap
will print a line saying so, rather than being silent. Naturally, this breaks a 
bunch of generic fstests but I've attached fixes for them. The code also comes
with xfstests. Furthermore, I've verified that none of the generic tests fail 
with this implementation apart from those tests which I've fixed. 

V2: Considered all of Darrick's review for the preivous posting, as a result 
this is being posted as the fiemap patches coupled with the xfstest patches.
