I don't think so.  While the naming of the helper is a bit
unfortunate, it is intended for allocating arrays.

But this function really should not exist, instead bitmap_alloc/free
should be switched to th kvmalloc family so that it will just work
for large allocations and we can kill the wrappers in XFS.
