Hi,
I have compiled the kernel with below given modification in .config
CONFIG_CMDLINE="uhash_entries=256"
After booting with the new kernel, the "kmemleak" no longer complains
about the "udp_table_init".
However it do report another possible leak :)
debian-mips:~# cat /sys/kernel/debug/kmemleak
unreferenced object 0x8f085000 (size 4096):

I completely agree with Daniel. Shall we move on and integrate the
kmemleak support for MIPS ?
Cheers,
