[v3,14/14] btrfs-progs: tests/mkfs: Check error handler for rootdir parameter

Commit Message

Qu Wenruo Sept. 18, 2017, 7:21 a.m. UTC

Error handlers for the following case must fail gracefully:
1) No permission to read content of rootdir
2) Too small destination file
3) Non-existent destination file
4) Zero sized destination file
