nfsd: Return the correct number of bytes written to the file
We must allow for the fact that iov_iter_write() could have returned a short write (e.g. if there was an ENOSPC issue). Fixes: d890be159a71 "nfsd: Add I/O trace points in the NFSv4 write path" Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
