Revision f555befd185dc097ede887eb7b308c2e1c1369d4 authored by Jan Stancek on 12 January 2021, 23:49:21 UTC, committed by Linus Torvalds on 13 January 2021, 02:12:54 UTC
After commit 236c32eb1096 ("mm: migrate: clean up migrate_prep{_local}")', do_migrate_pages can return uninitialized variable 'err' (which is propagated to user-space as error) when 'from' and 'to' nodesets are identical. This can be reproduced with LTP migrate_pages01, which calls migrate_pages() with same set for both old/new_nodes. Add 'err' initialization back.
