Hide internal fadvise64/fallocate64 functions [BZ #18822]
Hide internal fadvise64/fallocate64 functions to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * sysdeps/unix/sysv/linux/posix_fadvise64.c (__posix_fadvise64_l64): Add Add libc_hidden_proto and libc_hidden_def. * sysdeps/unix/sysv/linux/posix_fallocate64.c (__posix_fallocate64_l64): Likewise.
