Revision 474466301dfd8b39a10c01db740645f3f7ae9a28 authored by Hugh Dickins on 25 June 2021, 01:39:20 UTC, committed by Linus Torvalds on 25 June 2021, 02:40:53 UTC 
mm: page_vma_mapped_walk(): use goto instead of while (1)
 
page_vma_mapped_walk() cleanup: add a label this_pte, matching next_pte,
and use "goto this_pte", in place of the "while (1)" loop at the end.
