Re: [PATCH v3 1/7] selftests/mm: hugepage-shm: conform test to TAP format output

Hi Andrew,

There hasn't been any comment on these. I guess, they can be picked up now?

Thanks,

Conform the layout, informational and status messages to TAP. No functional change is intended other than the layout of output messages.

The "." was being printed inside for loop to indicate the writes progress. This was extraneous and hence removed in the patch.
