From daa3fc9bff55c1f8368a464ec802ab620901344e Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Tue, 22 Jun 2021 09:50:27 +0200 Subject: rt: Move generic implementation from sysdeps/pthread to rt The pthread-based implementation is the generic one. Replacing the stubs makes it clear that they do not have to be adjusted for the libpthread move. Result of: git mv -f sysdeps/pthread/aio_misc.h sysdeps/generic/ git mv sysdeps/pthread/timer_routines.c sysdeps/htl/ git mv -f sysdeps/pthread/{aio,lio,timer}_*.c rt/ Followed by manual adjustment of the #include paths in sysdeps/unix/sysv/linux/wordsize-64, and a move of the version definitions formerly in sysdeps/pthread/Versions.
