If there's real userspace (not just a test suite) which actually relies
on the exact errno returned, we can change the places which currently
just return the errno to something like:
if (err == -EBUSY)
return -ENOSPC;
return err;
There are actually a number of places in the kernel which do the opposite
translation today, presumably because having a program print out "No
space left on device" was confusing.
If it's only the test-suite which cares, presumably the test suite can
be changed to treat EBUSY and ENOSPC as being equivalent errno values
for a given test.

Thanks! I'll resend after -rc1.
