Replace vmalloc() followed by copy_from_user() with vmemdup_user() to improve nilfs_ioctl_clean_segments() and nilfs_ioctl_set_suinfo(). Use kvfree() to free the buffers created by vmemdup_user(). Use u64_to_user_ptr() instead of manually casting the pointers and remove the obsolete 'out_free' label. No functional changes intended.

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.
