Subject: [PATCH 3.2.0-rc1 1/3] Making si_swapinfo exportable
Date: Wed,  4 Jan 2012 19:21:54 +0200	[thread overview]
Message-ID: <58b74a5014e323cebeb4d3654f7f8a18c2f8d132.1325696593.git.leonid.moiseichuk@nokia.com> (raw)
In-Reply-To: <cover.1325696593.git.leonid.moiseichuk@nokia.com>
In-Reply-To: <cover.1325696593.git.leonid.moiseichuk@nokia.com>

If we will make si_swapinfo() exportable it could be called from modules.
Otherwise modules have no interface to obtain information about swap usage.
Change made in the same way as si_meminfo() declared.
