[LTP] [PATCH v5] Add ioctl_ficlone04 test

[LTP] [PATCH v5] Add ioctl_ficlone04 test

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

This test verifies that ioctl() FICLONE/FICLONERANGE feature raises
the right error according with bad file descriptors.

Signed-off-by: Andrea Cervesato <andrea.cervesato@suse.com>
---
This testing suite is testing ioctl() FICLONE and FICLONERANGE
functionalities. In particular, file clone and error codes.
---
Changes in v5:
- ioctl_ficlone04: TINFO on skip message, fix mail between <>
- Link to v4: https://lore.kernel.org/r/20240726-ioctl_ficlone-v4-1-710ed71bee70@suse.com

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
