+ *
+ * Description:
+- * Merges two queue_limit structs. Returns 0 if alignment didn't
+- * change. Returns -1 if adding the bottom device caused
+- * misalignment.
++ * This function is used by stacking drivers like MD and DM to ensure
++ * that all component devices have compatible block sizes and
++ * alignments. The stacking driver must provide a queue_limits
++ * struct (top) and then iteratively call the stacking function for
++ * all component (bottom) devices. The stacking function will
++ * attempt to combine the values and ensure proper alignment.
++ *
++ * Returns 0 if the top and bottom queue_limits are compatible. The
++ * top device's block sizes and alignment offsets may be adjusted to
++ * ensure alignment with the bottom device. If no compatible sizes
++ * and alignments exist, -1 is returned and the resulting top
++ * queue_limits will have the misaligned flag set to indicate that
++ * the alignment_offset is undefined.
