Subject: libfio: add runstate names
X-Git-Tag: fio-2.2.10~34
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=6e760cf3906d0942715c3c0de43040c53c0b8a92

libfio: add runstate names

Enables --debug=process to show the actual transitions, instead of
numbers you have to look up in the source:

process  12113 pid=12123: runstate CREATED -> INITIALIZED

instead of

process  12113 pid=12123: runstate 1 -> 2
