Subject: [PATCH v2 1/8] mm/swap: Fix kernel message in swap_info_get()
Date: Thu, 20 Oct 2016 16:31:40 -0700	[thread overview]
Message-ID: <b0e165c81fa73a515f2aa01bfb4c693636360da6.1477004978.git.tim.c.chen@linux.intel.com> (raw)
In-Reply-To: <cover.1477004978.git.tim.c.chen@linux.intel.com>
In-Reply-To: <cover.1477004978.git.tim.c.chen@linux.intel.com>

From: "Huang, Ying" <ying.huang@intel.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.
