Date: Thu, 13 Jan 2022 03:09:55 +0000 [thread overview] Message-ID: <email@example.com> (raw) [-- Attachment #1: Type: text/plain, Size: 418 bytes --] Hello, I'm a little confused about the usefulness of __vm_lock. It seems like that __vm_lock was originally cited to prevent the data race condition between pthread_barrier_wait and virtual memory changing, but it can not ensure that the virtual memory of the barrier will not be changed before pthread_barrier_wait. So, what is the meaning that introduce the __vm_lock to prevent the data race? Thank you. [-- Attachment #2: Type: text/html, Size: 3050 bytes --]
