V3.10-rc1 memory leak

[Larry Finger <Larry.Finger@lwfinger.net>]

Using v3.10-rc1-68-g2d3ec09, I am getting many instances of the following from 
kmemleak:

unreferenced object 0xffff8800b546dc30 (size 48):
   comm "systemd-udevd", pid 2181, jiffies 4294899141 (age 274.096s)

These appear to be real leaks, but I am not familiar with this section of the 
code, and they could be false indications.

This mail is sent to all authors of patches incorporated in 
kernel/trace/trace_events.c in 2013. Kernel 3.9 did not show this problem.

Thanks,
