| Subject: SCSI: fc-transport: Use packed modifier for fc_bsg_request structure. |
| |
| From: Harish Zunjarrao <harish.zunjarrao@qlogic.com> |
| |
| commit eda05a28ec52be40086400a1b606d211276f0e41 upstream. |
| |
| The 32bit kernel does not add padding bytes in the fc_bsg_request structure |
| whereas the 64bit kernel adds padding bytes in the fc_bsg_request structure. |
| Due to this, structure elements gets mismatched with 32bit application and |
| 64bit kernel.To resolve this, used packed modifier to avoid adding padding bytes. |
