	Again, I'm sorry, missing another not. I.e. I suppose normal users will not try
	to go below 301MB, therefore LTP probably should not do it either. That's why

@Darrick, others (kernel/LTP maintainers, embedded folks) WDYT?

I'm personally OK to use 300 MB (safer to use code paths which are used in
production), it's just that for older kernels even with xfs-progs installed it's
unnecessary boundary. We could base XFS size on runtime kernel, but unless it's
300 MB a real problem for anybody I would not address it. i.e. is there anybody
using XFS on old kernels? (old LTS, whey sooner or later need to use these
variables themselves).

Kind regards,
