filecopymethod-test.yml

# Some platform-specific file copy syscalls (e.g. creating reflinks) are only
# supported on some platforms, and only with specific filesystems. These
# syscalls are used by different FileCopyMethod implementations.
#
# This workflow sets up the conditions needed for those syscalls to work,
# and then runs the tests with the different FileCopyMethods.
