[LTP] [PATCH 2/2] syscalls/unshare: convert unshare02 to the new API

[xieziyao <xieziyao@huawei.com>]

Hi,

I just re-checked the latest code and made changes on your suggestions:
1. Add setup() and cleanup() to set uid to "nobody" for EPERM tests;
2. Modify the incorrect code style.

Please see: https://patchwork.ozlabs.org/project/ltp/patch/20210420072939.202584-1-xieziyao@huawei.com/

Thanks so much for your review!

Best Regards,
Ziyao

The EPERM check fails if the test is executed by a root. LTP tests usually setuid() to "nobody" for EPERM tests if executed as a root.

The TC should be lowercase but that is very minor.

Apart from these it's a really good cleanup.
