Commit Message

Lakshmipathi.G Oct. 14, 2019, 5:51 p.m. UTC

Make use of GitLab-CI nested virutal environment to start QEMU instance inside containers 
and perform btrfs-progs build, execute unit test cases and save the logs.

More details can be found at https://github.com/kdave/btrfs-progs/issues/171
