[PATCH 2/4] cifs: Simplify reparse point check in cifs_query_path_info() function
From: Pali Rohár
Date: Fri Dec 27 2024 - 12:39:21 EST
For checking if path is reparse point and setting data->reparse_point
member, it is enough to check if ATTR_REPARSE is present.
It is not required to call CIFS_open() without OPEN_REPARSE_POINT and
checking for -EOPNOTSUPP error code.
