Target Milestone: ---
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc has
#include <sys/ustat.h>
...
#if SANITIZER_LINUX && !SANITIZER_ANDROID
unsigned struct_ustat_sz = sizeof(struct ustat);
unsigned struct_rlimit64_sz = sizeof(struct rlimit64);
unsigned struct_statvfs64_sz = sizeof(struct statvfs64);
#endif // SANITIZER_LINUX && !SANITIZER_ANDROID
But <sys/ustat.h> has been removed from glibc 2.28 by

Deprecate ustat syscall interface
As for sysctl, ustat has been deprecated in favor of {f}statfs. Also
some newer ports which uses generic interface builds a stub version that
returns ENOSYS.
This patch deprecates ustat interface by removing ustat.h related headers,
adding a compatibility symbol, and avoiding new ports to build and provide
the symbol.
Checked on x86_64-linux-gnu and i686-linux-gnu. Also checked with a
check-abi on all affected ABIs.
