> This testing suite is testing ioctl() FICLONE and FICLONERANGE
> functionalities. In particular, file clone and error codes.
> ---
> Changes in v4:
> - ioctl_ficlone04: add EPERM and EOPNOTSUP
> - Link to v3: https://lore.kernel.org/r/20240724-ioctl_ficlone-v3-1-bdf7551380ee@suse.com
> 
> Changes in v3:
> - ioctl_ficlone04: use a generic array for expected errors
> - Link to v2: https://lore.kernel.org/r/20240723-ioctl_ficlone-v2-0-33075bbc117f@suse.com
> 
> Changes in v2:
> - add fallback definitions
> - algorithm steps using '-'
> - avoid assigning -1 to file descriptors after close()
> - use SAFE_UNLINK() instead of remove()
> - enable both xfs and btrs for all tests
> - Link to v1: https://lore.kernel.org/r/20240530-ioctl_ficlone-v1-0-fa96f07d0fca@suse.com
