Subject: [PATCH RESEND] staging: android: lowmemorykiller: set TIF_MEMDIE before send kill sig
Date: Fri, 14 Feb 2014 14:03:56 +0800 [thread overview]
Message-ID: <000001cf294a$b1bebd60$153c3820$%yang@samsung.com> (raw)
Set TIF_MEMDIE tsk_thread flag before send kill signal to the
selected thread. This is to fit a usual code sequence and avoid
potential race issue.
