- - pte_offset_map_nolock() - maps PTE, returns pointer to PTE with pointer to its PTE table - lock (not taken), or returns NULL if no PTE table; - pte_offset_map_ro_nolock() maps PTE, returns pointer to PTE with pointer to its PTE table lock (not taken), or returns NULL ...
In copy_pte_range(), we may modify the src_pte entry after holding the src_ptl, so convert it to using pte_offset_map_rw_nolock(). Since we may free the PTE page in retract_page_tables() without holding the read lock of mmap_lock, so we still need to get pmdval and do pmd_...
