fs/romfs/inode.c: trivial improvements

55ca3e79 · WANG Cong <[email protected]> · 2007-10-16 23:26:15 -07:00

- There are no lists in fs/romfs/inode.c, so using list_entry
  is a bit confusing.  Replace it with container_of.

- It is unnecessary to cast the return value of
  kmem_cache_alloc, since it returns a void* pointer.
