[PATCH blktests 1/4] check: fix exit status code handling

[Shin'ichiro Kawasaki]

Commit e50a5ff644f3 ("check: call _unload_module() after
fallback_device_cleanup()") added a _unload_module() call to
_check_and_call(). However, after this commit, _check_and_call() no
longer returns the exit status of _call_test(). Then, the check script
does not return non-zero exit status even when any test case fails. Fix
this by adding a local variable to keep the exit status of _call_test().

[PATCH blktests 2/4] nvme/rc: use _set_attr() in _create_nvmet_passthru()

[Shin'ichiro Kawasaki]

Commit 91316870b124 ("common/nvme, nvme/rc: use _set_attr() to trace
attribute writes") replaced sysfs/confgfs/debugfs attribute writes with
_set_attr() function call, but it missed to one place. Replace the
missed write.

[PATCH blktests 3/4] CONTRIBUTING: clarify that GPL-2.0 is not applicable

[Shin'ichiro Kawasaki]

Majority of the blktests code has GPL-3.0+, so the effective main
license is GPL-3.0+ (e.g., check, common/rc). However, GPL-2.0 and
GPL-3.0 are not compatible with each other [1]. Because the majority of
blktests is GPL-3.0+, blktests cannot contain GPL-2.0 files. All files
shall be GPL-3.0+ or GPL-2.0+. Document this requirement for
clarification.

[PATCH blktests 4/4] new: guide long command options

[Shin'ichiro Kawasaki]

In the past, command option confusion caused a script bug. The command
option definition change and command option misunderstanding were the
cause. To avoid such troubles, guide to use long command options.
