The xfs_printk in xfs_alert_tag doesn't need an XFS: prefix
as it's added by xfs_printk.

Add format checking to the non-debug inline function xfs_debug.
Miscellaneous function prototype argument alignment.

This seems like three very minor changes, but I actually
have something to say about each...

I'll highlight the fact that this was the last caller of
xfs_printk().  As such I think it should just be eliminated,
and make the use of xfs_info() or xfs_debug() mandatory.
They are clean, easy, and have meaningful enough names
that this should be fine.  (What do others think?)

This is a silly white space change, and I guess I don't care
either way.  But I think much of the XFS code tab-aligns
things that wrap to successive lines.

How about:

static inline void
__attribute__ ((format (printf, 2, 3)))
xfs_debug(const struct xfs_mount *mp, const char *fmt, ...)
{
}

I only wanted to point out the unnecessary "XFS:" duplication.
Taking out xfs_printk would save some text & data.
Do what you think appropriate.
