Date: Fri, 17 Apr 2015 10:59:42 +0300 From: Konstantin Belousov <kostikbel@gmail.com> To: arch@freebsd.org Cc: peter@freebsd.org Subject: Removal of the 6.x kernel compat code from libc Message-ID: <20150417075942.GI2390@kib.kiev.ua>
next in thread | raw e-mail | index | archive | help
Our libc changes in sync with the kernel, but switching of libc to use
new interfaces means that upgrade of the userspace becomes the flag day.
People usually add backward-compatible shims for libc to use older
interfaces on old kernels.
There is no reason to keep the compat shims after many years of the
transition. Patch below purges the compat code for pre-r171219, which
added pad-less versions of syscalls taking off_t, and for r177911, which
handles the struct flock/oflock transition. This is 6.x/7.x compat,
we absolutely not support running HEAD libc on such old kernels.
