Since commita166563e7e("arm64: mm: support large block mapping when rodata=full"), __change_memory_common has more chance to fail due to memory allocation failure when splitting page table. So check the return value of set_memory_rox(), then bail out if it fails otherwise we may have RW memory mapping for kprobes insn page.

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.
