a8410a5fc9
This patch consolidates all the non cancellable waitpid calls to use the __waitpid_nocancel identifier. For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * libio/ioopen.c (_IO_waitpid): Replace waitpid_not_cancel with __waitpid_nocancel. * sysdeps/generic/not-cancel.h (waitpid_not_cancel): Remove macro. (__waitpid_nocancel): New macro. * sysdeps/unix/sysv/linux/not-cancel.h (waitpid_not_cancel): Remove macro. (__waitpid_nocancel): Replace macro with a function. * sysdeps/unix/sysv/linux/waitpid.c (__waitpid_nocancel): New function.
