Hi, LTP test migrate_pages02 [1] is failing with 4.15-rcX, presumably as consequence of: 313674661925 "Unify migrate_pages and move_pages access checks" The scenario is that privileged parent forks child, both parent and child change euid to nobody and then parent tries to migrate child to different node. Starting with 4.15-rcX it fails with EPERM. Can anyone comment on accuracy of this sentence from man-pages after commit 313674661925? quoting man2/migrate_pages.2: "To move pages in another process, the caller must be privileged (CAP_SYS_NICE) or the real or effective user ID of the calling process must match the real or saved-set user ID of the target process."
