It is possible to double free the vm_ctx->mmu_ctx object in this function. 630 err_page_table_destroy: --> 631 pvr_mmu_context_destroy(vm_ctx->mmu_ctx); The pvr_vm_context_put() function does: kref_put(&vm_ctx->ref_count, pvr_vm_context_release); Here the pvr_vm_context_release() will call: pvr_mmu_context_destroy(vm_ctx->mmu_ctx); Refactor to an unwind style.

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 Restructured Text 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.
