Slab bug during skb allocation

[Md Muazzam Husain <mdmuazzamhusain@xxxxxxxxx>]

Hi All,

         I have kernel version 3.10.59. So during the allocation for skb i am getting call trace for __netdev_alloc_skb which follows till cache_alloc_refill and finally crashes. Please find snapshot below.

addr2line -e vmlinux ffffffffc114109c shows linux/mm/slab.c:2700 has the problem. Is there any existing bug and any patch for this.

Call Trace:
