Message-ID: <20131016124312.GF19729@linux.vnet.ibm.com> Date: Wed, 16 Oct 2013 18:13:12 +0530 From: Srikar Dronamraju <srikar@...ux.vnet.ibm.com> To: Oleg Nesterov <oleg@...hat.com> Cc: Ingo Molnar <mingo@...e.hu>, Anton Arapov <aarapov@...hat.com>, David Smith <dsmith@...hat.com>, "Frank Ch.

So this patch > adds the new "vaddr" argument to __create_xol_area() which should > be used as area->vaddr if it is nonzero. > > xol_add_vma() doesn't bother to verify that the predefined addr is > not used, insert_vm_struct() should fail if find_vma_links() detects > the overlap with the existing vma. > > Also, __create_xol_area() doesn't need __GFP_ZERO to allocate area. > > Cc: stable@...r.kernel.org # 3.9+ > Signed-off-by: Oleg Nesterov <oleg@...hat.com> Acked-by: Srikar Dronamraju <srikar@...ux.vnet.ibm.com> -- Thanks and Regards Srikar Dronamraju -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
