[LTP] [PATCH v3 3/7] syscalls/swapon03: use tst_max_swapfiles() and GET_USED_SWAPFILES() api

[Petr Vorel]

Hi Yang Xu,

> +	if (tst_fs_type(".") == TST_TMPFS_MAGIC)
> +		tst_brk(TCONF, "swap not supported on tmpfs");

This is based on my patchset:
https://patchwork.ozlabs.org/project/ltp/patch/20240205022857.191692-2-pvorel@suse.cz/

I still wonder why this is needed. Some problem of the loop device on tmpfs or
what? Also, as it's a separate unrelated change, shouldn't we merge my commit
instead?

Kind regards,
Petr
