Xiao Ni adfbb8ebd5 Update to latest upstream and fix mdcheck service bug
If mdcheck_start service can finish check action, it doesn't need to start mdcheck_continue
service. So in rhel only patch mdcheck.patch, we stop mdcheck_continue timer.

And there is a history problem. It needed KillMode=none before, so it removed
the upstream patch 52c67fcdd. Now this problem has been fixed, so we can do the
backport more easilly now. We don't need to remove the upstream patch here again.

Resolves: rhbz#2116418, rhbz#2150862, rhbz#2159584

Subject: [PATCH 112/125] mdopen: always try create_named_array()
mdopen() will use create_named_array() to ask the kernel to create the
given md array, but only if it is given a number or name.
If it is NOT given a name and is required to choose one itself using
find_free_devnm() it does NOT use create_named_array().
On kernels with CONFIG_BLOCK_LEGACY_AUTOLOAD not set, this can result in
failure to assemble an array. This can particularly seen when the
"name" of the array begins with a host name different to the name of the
host running the command.
So add the missing call to create_named_array().
