When BPF program invokes bpf_cpumask_release(), the migration must have
been disabled. When bpf_cpumask_release_dtor() invokes
bpf_cpumask_release(), the caller bpf_obj_free_fields() also has
disabled migration, therefore, it is OK to remove the unnecessary
migrate_{disable|enable} pair in bpf_cpumask_release().

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.
