With later hashmap example, using bpftool xlated output may
look like:
int dump_task(struct bpf_iter__task * ctx):
; struct task_struct *task = ctx->task;
0: (79) r2 = *(u64 *)(r1 +8)
; if (task == (void *)0 || called > 0)
...
19: (18) r2 = subprog[+17]
30: (18) r2 = subprog[+25]
...
36: (95) exit
__u64 check_hash_elem(struct bpf_map * map, __u32 * key, __u64 * val,
struct callback_ctx * data):
; struct bpf_iter__task *ctx = data->ctx;
37: (79) r5 = *(u64 *)(r4 +0)
...
55: (95) exit
__u64 check_percpu_elem(struct bpf_map * map, __u32 * key,
__u64 * val, void * unused):
; check_percpu_elem(struct bpf_map *map, __u32 *key, __u64 *val, void *unused)
56: (bf) r6 = r3
...
83: (18) r2 = subprog[-47]

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.
