oom-kill: show virtual size and rss information of the killed process
In a typical oom analysis scenario, we frequently want to know whether the
killed process has a memory leak or not at the first step. This patch
adds vsz and rss information to the oom log to help this analysis. To
save time for the debugging.
example:
===================================================================
rsyslogd invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0
Pid: 1308, comm: rsyslogd Not tainted 2.6.32-rc6 #24
Call Trace:
