Update.
* sysdeps/generic/utmp_file.c: Use not-cancelable syscalls all over the place. It would be allowed to have these fucntions as cancellation points but the cleanup would be ugly and a lot of work. * sysdeps/generic/not-cancel.h (fcntl_not_cancel): Define. * sysdeps/unix/sysv/linux/not-cancel.h (fcntl_not_cancel): Define. * include/fcntl.h (__fcntl_nocancel): Declare. * sysdeps/unix/sysv/linux/fcntl.c: New file. * sysdeps/unix/sysv/linux/i386/fcntl.c (__libc_fcntl): Only enable cancellation if absolutely needed. (__fcntl_nocancel): Define. * posix/unistd.h (gethostid): Remove __THROW. Clarify comment. * sysdeps/unix/sysv/linux/Makefile (CFLAGS-gethostid.c): Add -fexceptions. * sysdeps/unix/sysv/linux/gethostid.c (gethostid): Use extend_alloca. * resolv/res_init.c (__res_nclose): Use close_not_cancel_no_status instead of __close.
