Subject: mm-add-swap-slot-free-callback-to-block_device_operations-fix
From: Nitin Gupta <ngupta@xxxxxxxxxx>
A block device makes swap_slot_free_notify() callback when the last
reference to a swap slot is dropped.
This callback is made under swap_lock and sometimes page table lock. This
is a note of warning for registered callback function which must meet
these constraints.
