Memory leaks in Samsung's kernel

[Michał Akaanonim]

Hi,
I'm developing custom kernel for my Samsung Galaxy Ace 2 phone.
First, I'd like to check if there are any bugs, so I built kernel with
kmemleak enabled and I get 10 entries, for example:

unreferenced object 0xce2a2000 (size 8192):
  comm "vold", pid 1855, jiffies 4294942835 (age 1394.240s)
  hex dump (first 32 bytes):
    00 00 00 00 24 7e 50 c0 d0 7d 50 c0 7c 7d 50 c0  ....$~P..}P.|}P.
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
  backtrace:
    [<c03f4a00>] create_object+0x10c/0x24c
    [<c08e99f0>] kmemleak_alloc+0x6c/0xd0

    [<c06b3ffc>] table_load+0x114/0x2c4
    [<c06b37d4>] dm_ctl_ioctl+0x1d0/0x2cc

I noticed that in 6 of 10 entries there are dm_ctl_ioctl, table_load and
dm_table_add_target functions. So I think something is wrong with MD driver
but I compared source of this driver with other find on net and there
aren't any differences.
Source code of my kernel can be found here:

Thanks for any help.
Greetings, Michal.
