[patch 1/2] xen-gntalloc: integer overflow in gntalloc_ioctl_alloc()
On 32 bit systems a high value of op.count could lead to an integer overflow in the kzalloc() and gref_ids would be smaller than expected. If the you triggered another integer overflow in "if (gref_size + op.count > limit)" then you'd probably get memory corruption inside add_grefs().

[PATCH][RFC][12+2][v3] A expanded CFQ scheduler for cgroups
This patchset expands traditional CFQ scheduler in order to support cgroups, and improves old version. Improvements are as following. * Modularizing our new CFQ scheduler. The expanded CFQ scheduler is registered/unregistered as new I/O elevator scheduler called "cfq-cgroups". By this, the traditional CFQ scheduler, which does not handle cgroups, and our new CFQ
