Grygorii Maistrenko 9ac38e30f2 slub: do not merge cache if slub_debug contains a never-merge flag ... [ Upstream commit c6e28895a4372992961888ffaadc9efc643b5bfe ] In case CONFIG_SLUB_DEBUG_ON=n, find_mergeable() gets debug features from commandline but never checks if there are features from the SLAB_NEVER_MERGE set. As a result selected by slub_debug caches are always mergeable if they have been created without a custom constructor set or without one of the SLAB_* debug features on. This moves the SLAB_NEVER_MERGE check below the flags update from commandline to make sure it won't merge the slab cache if one of the debug features is on.
