While reviewing LTP testcases I've found that we still carry workaround
for 17 years old distributions that attempted to start bdflush from
userspace. I guess it's about the time to remove it.

I've tested the patch on i386. Before the patch calling bdflush() with
attempt to tune a variable returned 0 and after the patch the syscall
fails with EINVAL. You can use the now deleted LTP bdflush testcase for
testing:

https://github.com/linux-test-project/ltp/commit/53ede74305ff7f6498d7456b6e3ea3053ed4b7dd

Also I'm not 100% sure that I patched all the syscall tables correctly,
so this needs a proper review from arch maintainers.

Should be ENOSYS, doesn't it?

My bad, the LTP syscall wrapper handles ENOSYS and produces skipped
results based on that.

EINVAL is what you get for not yet implemented syscalls, i.e. new
syscall on old kernel.

EINVAL?  Is that a bdflush-specific thing, test-specific, or is itmore
general?

glibc has fallback paths that test for ENOSYS only.  EINVAL will be
passed to the application, skipping fallback.  For missing system calls,
this is not what we want.

Thanks,
Florian

The syscall returns ENOSYS after this change, sorry for the confusion.
