Subject: copy: ignore -EOPNOTSUPP from copy_file_range()
X-Git-Tag: v256-rc1~124

copy: ignore -EOPNOTSUPP from copy_file_range()

According to copy_file_range (2), errno will be set to EOPNOTSUPP when
the file system does not support copy_file_range(). Since there is
already fallback logic in place here for other kinds of errors, add
-EOPNOTSUPP to the list of ignored errors.
