c647fb885c
This patch consolidates all the non cancellable write calls to use the __write_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. * sysdeps/generic/not-cancel.h (write_not_cancel): Remove macro. (__write_nocancel): New macro. * sysdeps/unix/sysv/linux/not-cancel.h (__write_nocancel): Rewrite as a function prototype. (write_not_cancel): Remove macro. * sysdeps/unix/sysv/linux/write.c (__write_nocancel): New function. * gmon/gmon.c (ERR): Replace write_not_cancel with __write_nocancel. (write_gmon): Likewise. * libio/fileops.c (_IO_new_file_write): Likewise. * login/utmp_file.c (pututline_file): Likewise. (updwtmp_file): Likewise. * stdio-common/psiginfo.c (psiginfo): Likewise. * sysdeps/posix/spawni.c (__spawni_child): Likewise. * sysdeps/unix/sysv/linux/gethostid.c (sethostid): Likewise. * sysdeps/unix/sysv/linux/libc_fatal.c (backtrace_and_maps): Likewise. * sysdeps/unix/sysv/linux/pthread_setname.c (pthread_setname_np): Likewise.
