# NOTE : how to update the expected value ranges
# When new metrics appear use this to determine what resonable differences
# may be expected:
#
# echo "DELTAS:"
# cat $tmp.delta
# echo ""
# Here is where to paste the new values AFTER adjusting them to multiples of
# the expected minimum delta (nfiles). Values less than the minimum delta
# should NOT appear.
#
# Things to beware of!
#
# 1. Use only nondeterministic metrics. Some metrics rely on kernel data
# structures which may or not be populated with the "right" objects when the
# test is run e.g. things like "allocated from free list" vs "allocated new".
#
# 2. Different versions of the kernel may have different paths through the
# statistics gathering code. Be conservative in the minima you set below.
# The test must work on all of them. If possible, try on a variety of kernels.
# E.g. if x.y.z returns 758 on IRIX 6.1 and 516 on IRIX 5.3 the minimum should
# be set to 500.
#
# 3. Use a quiescent system!
#
# DO NOT INCREASE THESE FIGURES WITHOUT CHECKING THE OUTPUT ON 5.3 and 6.1
#
# Nondeterministic metrics zeroed in list below:
# bmapfbc, itobpf, found
