Subject: selftests/mm: hugepage-shm: conform test to TAP format output
Date: Fri, 26 Jan 2024 16:21:20 +0500
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.
