[PATCH 0/5] asm-generic: strncpy_from_user/strnlen_user cleanup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

As I've queued up some patches for include/asm-generic/unistd.h, I
remembered an older series that I created but never submitted.

These two functions appear to be unnecessarily different between
architectures, and the asm-generic version is a bit questionable,
even for NOMMU architectures.

Clean this up to just use the generic library version for anything
that uses the generic version today.

Arnd Bergmann (5):
  asm-generic/uaccess.h: remove __strncpy_from_user/__strnlen_user
  hexagon: use generic strncpy/strnlen from_user
  arc: use generic strncpy/strnlen from_user
  asm-generic: uaccess: remove inline strncpy_from_user/strnlen_user
  asm-generic: remove extra strn{cpy_from,len}_user declarations
