====================
Make libbpf support static initialization of BPF_MAP_TYPE_PROG_ARRAY
with a syntax similar to map-in-map initialization:
SEC("socket")
int tailcall_1(void *ctx)
{
return 0;
}
struct {
__uint(type, BPF_MAP_TYPE_PROG_ARRAY);
__uint(max_entries, 2);
__uint(key_size, sizeof(__u32));
__array(values, int (void *));
} prog_array_init SEC(".maps") = {
.values = {
[1] = (void *)&tailcall_1,
},
};
v1->v2:
- Add stricter checks on relos collect, some renamings (Andrii)
- Update selftest to check tailcall result (Andrii)

============
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.
