Subject: remove inclusion guard hacks for sys/kd.h
X-Git-Tag: v1.1.20~36
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=2fab90a71acd3698954c08b9062db67188443dd7;p=oweals%2Fmusl.git

remove inclusion guard hacks for sys/kd.h

maintainer's note: at some point, probably long before linux separated
the uapi headers, it was the case, or at least I believed it was the
case, that linux/types.h was unsafe to include from userspace. thus,
the inclusion guard macro _LINUX_TYPES_H was defined in sys/kd.h to
prevent linux/kd.h from including linux/types.h (which it spuriously
includes but does not use). as far as I can tell, whatever problem
this was meant to solve does not seem to have been present for a long
time, and the hack was not done correctly anyway, so removing it is
the right thing to do.
