After mounting a file system with a disabled OSC the import is left in the LUSTRE_IMP_NEW state without an imp_connection. When the OSC's import is read with lprocfs_rd_import the client will panic with a NULL pointer dereference.

Issue Links

• Trackbacks: Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA

Does this issue also apply to master? If so, could you please port the fix to master Bobijam? It should be possible to still show Jeremy as the original author of this code if you do so.
