From 3ab19e61b3adf550fd280fd6e0604da82368bd73 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 2 Mar 2018 10:31:25 +1100 Subject: [PATCH] staging: lustre: obdclass: don't require lct_owner to be non-NULL. Some places in lu_object.c allow lct_owner to be NULL, implying that the code is built in to the kernel (not a module), but two places don't. This prevents us from building lustre into the kernel. So remove the requirement and always allow lct_owner to be NULL. This requires removing an "assert" that the module count is positive, but this is redundant as module_put() already does the necessary test.
