Zhihao Cheng 3b185255bb ubi: fastmap: Don't produce the initial next anchor PEB when fastmap is disabled ... Following process triggers a memleak caused by forgetting to release the initial next anchor PEB (CONFIG_MTD_UBI_FASTMAP is disabled): 1. attach -> __erase_worker -> produce the initial next anchor PEB 2. detach -> ubi_fastmap_close (Do nothing, it should have released the initial next anchor PEB) Don't produce the initial next anchor PEB in __erase_worker() when fastmap is disabled.
