Basic overcommit checking for hugetlb_file_map() based on an implementation used with demand faulting in SLES9. Since demand faulting can't guarantee the availability of pages at mmap time, this patch implements a basic sanity check to ensure that the number of huge pages required to satisfy the mmap are currently available. Despite the obvious race, I think it is a good start on doing proper accounting. I'd like to work towards an accounting system that mimics the semantics of normal pages (especially for the MAP_PRIVATE/COW case). That work is underway and builds on what this patch starts. Huge page shared memory segments are simpler and still maintain their commit on shmget semantics.
