Yang Yingliang 6ad805b82d doc: fix documentation about UIO_MEM_LOGICAL using ... After commit d4fc5069a3 ("mm: switch s_mem and slab_cache in struct page") page->mapping will be re-used by slab allocations and page->mapping->host will be used in balance_dirty_pages_ratelimited() as an inode member but it's not an inode in fact and leads an oops.

But the documentation about UIO_MEM_LOGICAL allows using kmalloc(), remove and don't allow using kmalloc() in documentation.
