Subject: fio: make gauss a duplicate of normal for file_service_type
X-Git-Tag: fio-2.99~14
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=dd3503d365f87e68079fb3e443a410743688d53b

fio: make gauss a duplicate of normal for file_service_type

To be consistent with random_distribution add a normal parameter to
file_service_type and state that gauss is an alias of it.
