5.15-stable review patch. If anyone has any objections, please let me know.

From: Eric W. Biederman ebiederm@xmission.com
[ Upstream commit ca3574bd653aba234a4b31955f2778947403be16 ]
Update module_put_and_exit to call kthread_exit instead of do_exit.
Change the name to reflect this change in functionality. All of the users of module_put_and_exit are causing the current kthread to exit so this change makes it clear what is happening. There is no functional change.
