Linus Torvalds 9fb7007de8 Char/Misc patch for 5.5-rc6 ... Here is a single fix, for the chrdev core, for 5.5-rc6 There's been a long-standing race condition triggered by syzbot, and occasionally real people, in the chrdev open() path. Will finally took the time to track it down and fix it for real before the holidays. Here's that one patch, it's been in linux-next for a while with no reported issues and it does fix the reported problem.
