[PATCH v3] xfs: ensure f_ffree returned by statfs() is non-negative

[Christoph Hellwig]

Good changelog this time around, thanks.

> -       statp->f_ffree = statp->f_files - (sbp->sb_icount -
> sbp->sb_ifree);

Your mailer line-wrapper the patch here.

> +       ffree = statp->f_files - (sbp->sb_icount - sbp->sb_ifree);
> +       statp->f_ffree = (__u64) (ffree < 0 ? 0 : ffree);

Why not just use min_t here?

	statp->f_ffree = max_t(__int64_t, ffree, 0);
