Subject: [PATCH v2 1/8] mm/swap: Fix kernel message in swap_info_get()

From: "Huang, Ying" <ying.huang@...el.com>

swap_info_get() is used not only in swap free code path but also in
page_swapcount(), etc.  So the original kernel message in
swap_info_get() is not correct now.  Fix it via replacing "swap_free" to
"swap_info_get" in the message.
