[LU-1646] mounting lustre oops on older kernels

• Type: Bug
• Resolution: Duplicate

• Affects Version/s: Lustre 2.1.2
• Environment: sles10sp4

Description

in lustre 2.1 and up, the lustre_fill_super() was changed to expect the anonymous pointer to be of the type struct lustre_mount_data2. however, the ifdef for lustre_get_sb() for kernels < 2.6.18 was not updated. the attached patch seems to fix things but you might run into trouble when nfs exporting from these old kernels since lmd_mnt cannot be filled in for these older kernels.
