# This test checks that the filestreams allocator never allocates space in any
# given AG into more than one stream when there's plenty of space on the
# filesystem. Newer feature sets (e.g. reflink) have increased the size of
# the log for small filesystems, so we make sure there's one more AG than
# filestreams to encourage the allocator to skip whichever AG owns the log.
#
# Exercise 9x 22MB AGs, 4 filestreams, 8 files per stream, and 3MB per file.
