Yuntao Wang 28bbdca6a7 bpf: Fix incorrect memory charge cost calculation in stack_map_alloc() ... commit b45043192b3e481304062938a6561da2ceea46a6 upstream. 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 commit 370868107bf6 ("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.
