Hi again, I recently noticed that my slub-enabled kernel won't let me stop and restart the NFS server. It stops fine but on restart it returns -ENOMEM.
It turns out that this is because kmem_cache_create is failing because the name already exists in sysfs. fs/nfsd/nfs4state creates 4 kmem_caches. Two of them get shared: /sys/slab/nfsd4_files -> ../slab/eventpoll_pwq /sys/slab/nfsd4_stateids -> ../slab/kmalloc-128 When kmem_cache_destroy is called, the alias count is reduced properly, but the alias symlink does not get removed. So when we try to create those caches again, it fails. Not sure how best to fix this one.... kmem_cache_destroy currently doesn't know which alias is being destroyed.
