The kernel struct_ops obj has kernel's func ptrs implemented by bpf_progs.
The bpf prog_id is stored as the value of the func ptr for introspection
purpose. In the latter patch, a struct_ops dump subcmd will be added
to introspect these func ptrs. It is desired to print the actual bpf
prog_name instead of only printing the prog_id.
Since struct_ops is the only usecase storing prog_id in the func ptr,
this patch adds a prog_id_as_func_ptr bool (default is false) to
"struct btf_dumper" in order not to mis-interpret the ptr value
for the other existing use-cases.
While printing a func_ptr as a bpf prog_name,
this patch also prefix the bpf prog_name with the ptr's func_proto.
[ Note that it is the ptr's func_proto instead of the bpf prog's
func_proto ]
It reuses the current btf_dump_func() to obtain the ptr's func_proto
string.
Here is an example from the bpf_cubic.c:
"void (struct sock *, u32, u32) bictcp_cong_avoid/prog_id:140"

A char[] is currently printed as an integer array.
This patch will print it as a string when
1) The array element type is an one byte int
2) The array element type has a BTF_INT_CHAR encoding or
the array element type's name is "char"
3) All characters is between (0x1f, 0x7f) and it is terminated
by a null character.

Just like commit 4022e7af86, this fixes the fact that
IORING_OP_ACCEPT ends up using get_unused_fd_flags(), which checks
current->signal->rlim[] for limits.
Add an extra argument to __sys_accept4_file() that allows us to pass
in the proper nofile limit, and grab it at request prep time.

Dmitry reports that a test case shows that io_uring isn't honoring a
modified rlimit nofile setting. get_unused_fd_flags() checks the task
signal->rlimi[] for the limits. As this isn't easily inheritable,
provide a __get_unused_fd_flags() that takes the value instead. Then we
can grab it when the request is prepared (from the original task), and
pass that in when we do the async part part of the open.

This soc has two phy's for the pcie one of them using just a different
register for settig it up but sharing all the rest of the config. Until
now we was presenting this schema as three different phy's in the device
tree using the 'phy-cells' node property to discriminate an index and
setting up a complete phy for the dual port index. This sometimes worked
properly but reconfiguring the same registers twice presents sometimes
some unstable pcie links and the ports was not properly being detected.
The problems only appears on hard resets and soft resets was properly
working. Instead of having this schema just set two phy's in the device
ree and use the 'phy-cells' property to say if the port has or not a dual
port. Doing this configuration and set up becomes easier, LOC is decreased
and the behaviour also gets deterministic with properly and stable pcie
links in both hard and soft resets.
