Jeff Layton a608ca21f5 vfs: allocate page instead of names_cache buffer in mount_block_root ... First, it's incorrect to call putname() after __getname_gfp() since the bare __getname_gfp() call skips the auditing code, while putname() doesn't. mount_block_root allocates a PATH_MAX buffer via __getname_gfp, and then calls get_fs_names to fill the buffer. That function can call get_filesystem_list which assumes that that buffer is a full page in size. On arches where PAGE_SIZE != 4k, then this could potentially overrun. In practice, it's hard to imagine the list of filesystem names even approaching 4k, but it's best to be safe. Just allocate a page for this purpose instead. With this, we can also remove the __getname_gfp() definition since there are no more callers.
