In the Linux kernel, the following vulnerability has been resolved:

RDMA/restrack: Fix potential invalid address access

struct rdma_restrack_entry's kern_name was set to KBUILD_MODNAME
in ib_create_cq(), while if the module exited but forgot del this
rdma_restrack_entry, it would cause a invalid address access in
rdma_restrack_clean() when print the owner of this rdma_restrack_entry.

These code is used to help find one forgotten PD release in one of the
ULPs. But it is not needed anymore, so delete them.
