In raid1_reshape(), newpool is a stack variable. mempool_init() initializes newpool->wait with the stack address. After assigning newpool to conf->r1bio_pool, the wait queue need to be reinitialized, which is not ideal. Change raid1_conf->r1bio_pool to a pointer type and replace mempool_init() with mempool_create_kmalloc_pool() to avoid referencing a stack-based wait queue.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
