# Name    : exclude_loopdev_tests.sh
# Purpose : Generate list of tests which require loopdev so they can be
#           excluded in GitLab Docker CI images because loop device
#           creation fails.  Suitable for assigning directly to the
#           GTEST_FILTER environment variable.
# Usage   : export_GTEST_FILTER=`exclude_loopdev_tests.sh tests/test_SupportedFileSystems.cc`
