commit02f312754c("ntfs3: fix use-after-free of sbi->options in cmp_fnames") introduced a use-after-free bug due to improper handling of sbi->options in error paths. This resulted in crashes when superblock cleanup is performed in ntfs_put_super. This patch ensures that the options structure and its subfields are properly freed, preventing the memory corruption and use-after-free errors.

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.
