So that's might be > the problem? Thanks for confirming your use case. Well, "Testing only" in the help (-h) was added there to suggest it's for testing/debugging LTP, not a production testing. But newer mind, I'll implement Cyril's suggestion, real usage justify it. + I'll add LTP_FORCE_SINGLE_FS_TYPE. We could allow more filesystems, e.g. instead of running LTP few times with different LTP_SINGLE_FS_TYPE value: e.g. for fs in ext4 xfs btrfs; do LTP_SINGLE_FS_TYPE=fs ioctl_ficlone02; done we could introduce support for particular filesystems LTP_FILESYSTEMS="ext4,xfs,btrfs" ioctl_ficlone02 (Probably define new variable because "SINGLE" is misleading when supporting more filesystems. Also when we touch it, I would consider renaming variable FILESYSTEMS is more obvious for newcomers than "FS_TYPE".) WDYT?
