[PATCH 24/46] mtd: nandsim: Wire up NANDSIM_MODE_CACHEFILE ioctl mode

From: Daniel Walter
Date: Wed Aug 31 2016 - 03:35:25 EST


From: Richard Weinberger <richard@xxxxxx>

Allow the userspace control tool also to setup a cache file.
In contrast to the cache_file module parameter the ioctl() only
accepts a fd. So, userspace should hand in an fd pointing to
a temp file.
