| Subject: Fix problem recognizing symlinks |
| |
| From: Steve French <smfrench@gmail.com> |
| |
| commit 19e81573fca7b87ced7701e01ba164b968d929bd upstream. |
| |
| Changeset eb85d94bd introduced a problem where if a cifs open |
| fails during query info of a file we |
| will still try to close the file (happens with certain types |
| of reparse points) even though the file handle is not valid. |
| |
| In addition for SMB2/SMB3 we were not mapping the return code returned |
| by Windows when trying to open a file (like a Windows NFS symlink) |
| which is a reparse point. |
