linux-toradex.git/mm/frontswap.c, branch v6.0-rc6

docs: rename Documentation/vm to Documentation/mm

2022-06-27T19:52:53+00:00

so it will be consistent with code mm directory and with
Documentation/admin-guide/mm and won't be confused with virtual machines.

There is only a single instance of frontswap ops in the kernel, so
simplify the frontswap code by removing support for multiple operations.

frontswap: simplify frontswap_register_ops

2022-01-22T06:33:38+00:00

Given that frontswap_register_ops must be called from built-in code,
there is no need to handle the case of swapfiles coming online before or
during it, so delete the code that deals with that case.
