From: Arnd Bergmann <arnd@arndb.de> The get_user()/put_user() functions are meant to check for access_ok(), while the __get_user()/__put_user() functions don't. This broke in 4.19 for nds32, when it gained an extraneous check in __get_user(), but lost the check it needs in __put_user().
Looks good: Reviewed-by: Christoph Hellwig <hch@lst.de>
