[Test]Creating/Deleting sparse files should be consistent to reflect available space
Testcase: - note the current available space on the mount - create 1M file on the mount - note the current available space on the mountpoint and compare with space before creation - remove the file - note the current available space on the mountpoint and compare with space before creation Change-Id: Iff017039d1888d03f067ee2a9f26aff327bd4059 Co-authored-by: Vitalii Koriakov <vkoriako@redhat.com> Signed-off-by: Vitalii Koriakov <vkoriako@redhat.com> Signed-off-by: kshithijiyer <kshithij.ki@gmail.com>
