Provide the inner part of refill_stock() as __refill_stock() without disabling interrupts. This eases the integration of local_lock_t where recursive locking must be avoided. Open code obj_cgroup_uncharge_pages() in drain_obj_stock() and use __refill_stock(). The caller of drain_obj_stock() already disables interrupts.

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.
