commitb45043192bupstream. This is a backport of the original upstream patch for 5.4/5.10. The original upstream patch has been applied to 5.4/5.10 branches, which simply removed the line: cost += n_buckets * (value_size + sizeof(struct stack_map_bucket)); This is correct for upstream branch but incorrect for 5.4/5.10 branches, as the 5.4/5.10 branches do not have the commit370868107b("bpf: Eliminate rlimit-based memory accounting for stackmap maps"), so the bpf_map_charge_init() function has not been removed. Currently the bpf_map_charge_init() function in 5.4/5.10 branches takes a wrong memory charge cost, the attr->max_entries * (sizeof(struct stack_map_bucket) + (u64)value_size)) part is missing, let's fix it.

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.
