Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

tcf_act_police_init() can fail after the idr has been successfully
reserved (e.g., qdisc_get_rtab() may return NULL). When this happens,
subsequent attempts to configure a police rule using the same idr value
systematiclly fail with -ENOSPC:
# tc action add action police rate 1000 burst 1000 drop index 100
RTNETLINK answers: Cannot allocate memory
We have an error talking to the kernel
# tc action add action police rate 1000 burst 1000 drop index 100
RTNETLINK answers: No space left on device
We have an error talking to the kernel
# tc action add action police rate 1000 burst 1000 drop index 100

...
Fix this in the error path of tcf_act_police_init(), calling
tcf_idr_release() in place of tcf_idr_cleanup().
Fixes:

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
