Subject: [PATCH] drivers, vmw_balloon.c: Determine page allocation flag can_sleep outside loop.
Date: Tue, 18 Oct 2011 00:13:47 +0600 [thread overview]
Message-ID: <1318875227.10091.5.camel@localhost.localdomain> (raw)
In vmballoon_reserve_page function, flags has been passed from the callee function (vmballoon_inflate here). So, we can determine can_sleep outside the loop.
