Subject: 3.4-rc2: Possible memory leak in __register_sysctl_table()
Date: Fri, 13 Apr 2012 13:10:05 -0500	[thread overview]
Message-ID: <4F886BFD.7040007@lwfinger.net> (raw)

I am seeing apparent memory leaks in 3.4-rcX. I do not think I saw these in 3.3.

The kmemleak traceback is:

unreferenced object 0xffff8800b7536180 (size 96):
   comm "swapper/0", pid 1, jiffies 4294892617 (age 8756.084s)
   hex dump (first 32 bytes):
