Title:
  ubuntu_lttng_smoke_test , ubuntu_ltp_syscalls/fallocate06,
  ubuntu_ltp/fs:fs_fill failed on O-azure Standard_B1ms and gcp g1.small
  due to insufficient disk space

Status in ubuntu-kernel-tests:
  New

Bug description:
  Issue found on Azure instance Standard_B1ms with O-azure 6.11.0-1004.4
  after the build issue bug 2077134 has been fixed.

  In this test we will try to create a 2G file for the swap, and this
  attempt will fail because of the insufficient disk space.

  This disk space issue is affecting ubuntu_ltp_syscalls/fallocate06 and ubuntu_ltp/fs:fs_ill test on Standard_B1ms as well:
