I don't think so.  We have:

#  define POST_WRITE(p, s) COMMON_SYSCALL_POST_WRITE_RANGE(p, s)

and the description of COMMON_SYSCALL_POST_WRITE_RANGE is:

//   COMMON_SYSCALL_POST_WRITE_RANGE
//          Called in posthook for regions that were written to by the kern=
el
//          and are now initialized.

and, libsanitizer does *not* intercept syscalls, but intercepts libc calls.=
  So
the size value is used by determine if the *libc function call* will overwr=
ite
the buffer, and the size from glibc header shall be used, not the kernel
header.  The name "struct_kernel_stat_sz" is just misleading, should be
"struct_stat_sz" or "struct_libc_stat_sz".=
