If we get ERR_PTR() from get_link(), we are guaranteed to get err != 0
when we break out of do-while, so we are going to hit if (err) return err;
shortly after it. Pull that into the if (IS_ERR(s)) body.

Now that current->nameidata is available, nd_set_link() can
use that directly, so 'nd' doesn't need to be passed through
->follow_link.
As a result of this change, 'nameidata' is almost entirely
local to namei.c. It is only exposed externally as an opaque struct

task_struct currently contains two ad-hoc members for use by
the VFS: link_count and total_link_count.
These are only interesting to fs/namei.c, so exposing them
explicitly is poor layering.
This patches replaces those with a single pointer to 'struct
nameidata'.

From: NeilBrown
The only thing any ->put_link() function did with the
nameidata was to call nd_get_link() to get the link name.
So now just pass the link name directly.
This allows us to make nd_get_link() completely local to
namei.c.

While trying to test a Cinterion GSM/GPS/3G module I had reconfigured
the USB interface by mistake and therefore needed to run a different
USB driver than CDC-ACM. It turned out that I need the "usbserial" driver.
This file is an official description how to use it:

Add support for basic kernel probes(kprobes) and jump probes
(jprobes) for ARM64.
Kprobes utilizes software breakpoint and single step debug
exceptions supported on ARM v8.
A software breakpoint is placed at the probe address to trap the
kernel execution into the kprobe ha

Certain instructions are hard to execute correctly out-of-line (as in
kprobes). Test functions are added to insn.[hc] to identify these. The
instructions include any that use PC-relative addressing, change the PC,
or change interrupt masking. For efficiency and simplicity

AArch64 ISA does not have instructions to pop the PC register
value from the stack(like ARM v7 has ldmia {...,pc}) without using
one of the general purpose registers. This means return probes
cannot return to the actual return address directly without
modifying register cont
