SubjectV3.10-rc1 memory leak
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)
hex dump (first 32 bytes):
00 dc 46 b5 00 88 ff ff d0 ff 5b a0 ff ff ff ff ..F.......[.....
1c 3b 5b a0 ff ff ff ff 12 3a 5b a0 ff ff ff ff .;[......:[.....

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,

Larry
