Is that by default the EINTR is truned off in NFS? If so, I don't see that
will be a problem. Sorry for my limited knowledge, is there any
requirements/benefits that people turn on EINTR?

The problem is not restricted to file system. Actually my patched
version(only backend/storage) passed hundreds times of regression without
any problem, but EINTR can hurt other syscalls as well. Find out *all* the
EINTR situtations may need big efforts AFAICS.
