[PATCH v2 18/18] uaccess: drop maining CONFIG_SET_FS users

[Sergey Matyukevich]

Hi Arnd,

> From: Arnd Bergmann <arnd at arndb.de>
> 
> There are no remaining callers of set_fs(), so CONFIG_SET_FS
> can be removed globally, along with the thread_info field and
> any references to it.
> 
> This turns access_ok() into a cheaper check against TASK_SIZE_MAX.
> 
> With CONFIG_SET_FS gone, so drop all remaining references to
> set_fs()/get_fs(), mm_segment_t and uaccess_kernel().

> Signed-off-by: Arnd Bergmann <arnd at arndb.de>
