Re: [patch v2 3/4] x86, ptrace: prepare regset get/set routines for user specified lengths

[Roland McGrath]

This change is unnecessary and IMHO misguided.  The arch user_regset.get
and user_regset.set functions are not required to worry about bogus
arguments.  Their callers are required to pass values that don't violate
the .n, .size, and .align constraints in the user_regset.  The right place
to enforce these constraints on parameters coming from userland is in the
arch-independent code that calls the arch user_regset functions.


Thanks,
Roland
