[PATCH -V7 RESEND 02/21] swap: Add __swap_duplicate_locked()

2018-11-20 Thread Huang Ying
The part of __swap_duplicate() with lock held is separated into a new function __swap_duplicate_locked(). Because we will add more logic about the PMD swap mapping into __swap_duplicate() and keep the most PTE swap mapping related logic in __swap_duplicate_locked(). Just mechanical code
