Current comments to ac_g_ex, the member of struct
ext4_allocation_context is,
	/* goal request (after normalization) */
This is a little bit confused. In order to make it easier to be
understood, this patch modify the comments as,
	/* goal request (normalized ac_o_ex) */
which means ac_g_ex is a normalized value of ac_o_ex.
