Could we remove the "magic" sync_flag from the exported interface?

Do sth. like renaming your invalidate_dev() to
_invalidate_dev() and adding 3 defines:

#define invalidate_dev(dev) _invalidate_dev(dev,0)
#define invalidate_dev_sync(dev) _invalidate_dev(dev,1)
#define invalidate_dev_fsync(dev) _invalidate_dev(dev,2)

This would make it quite clear, what will be done.

AFAIR Linus dosn't like these magic numers either, right?
