[PATCH v2 8/8] termios: get rid of non-UAPI asm/termios.h

From: Al Viro
Date: Sat Aug 20 2022 - 21:03:06 EST


All non-UAPI asm/termios.h consist of include of UAPI counterpart
and, possibly, include of linux/uaccess.h

The latter can't be simply removed, even though nothing in
linux/termios.h doesn't depend upon it anymore - there are several
places that rely upon that indirect chain of includes to pull
linux/uaccess.h. So the include needs to be lifted out of there -
we lift into tty_driver.h, serdev.h and places that pull asm/termios.h,
but none of
* linux/uaccess.h (obvious)
* net/sock.h (pulls uaccess.h)
* linux/{tty,tty_driver,serdev}.h (tty.h pulls tty_driver.h)

That leaves us just with the include of UAPI asm/termios.h, which is
what <asm/termios.h> will resolve to if we simply remove non-UAPI header.
