allocate structures for reservation tracking in hugetlbfs outside of spinlocks v2
[Andrew this should replace the previous version which did not check the returns from the region prepare for errors. This has been tested by us and Gerald and it looks good.

Here is an updated patch to correct this. This passes testing here.] Signed-off-by: NAndy Whitcroft <apw@shadowen.org> Tested-by: NGerald Schaefer <gerald.schaefer@de.ibm.com> Cc: Mel Gorman <mel@csn.ul.ie> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
