The try_to_wake_up function has an optimization where it can queue
a task for wakeup on its previous CPU, if the task is still in the
middle of going to sleep inside schedule().
Once schedule() re-enables IRQs, the task will be woken up with an
IPI, and placed back on the runqueue.

Function sdev_store_queue_depth() enforces that the sdev queue depth cannot
exceed shost.can_queue.
However, the LLDD may still set cmd_per_lun > can_queue, which leads to an
initial sdev queue depth greater than can_queue.
Stop this happened by capping initial sdev queue depth at can_queue.

Changes since RFC:
- KVM_CAP_HYPERV_ENFORCE_CPUID introduced. Turns out that at least QEMU
is not doing a great job setting Hyper-V CPUID entries for various
configurations (when not all enlightenments are enabled).
- Added a selftest.
- Add Wei's A-b tag to PATCH1.
Currently, all implemented

Two helpers (trace_printk and seq_printf) have very similar
implementations of format string parsing and a third one is coming
(snprintf). To avoid code duplication and make the code easier to
maintain, this moves the operations associated with format string
parsing (validation and argument
The "positive" part tests all format specifiers when things go well.
The "negative" part makes sure that incorrect format strings fail at
load time.

The implementation takes inspiration from the existing bpf_trace_printk
helper but there are a few differences:
To allow for a large number of format-specifiers, parameters are
provided in an array, like in bpf_seq_printf.
Because the output string takes two arguments and the array of
parameters
Similarly to BPF_SEQ_PRINTF, this macro turns variadic arguments into an
array of u64, making it more natural to call the bpf_snprintf helper.

When initializing the __param array with a one liner, if all args are
const, the initial array value will be placed in the rodata section but
because libbpf does not support relocation in the rodata section, any
pointer in this array will stay NULL.
Fixes: c09add2fbc5a ("tools/libbpf: Add
This type provides the guarantee that an argument is going to be a const
pointer to somewhere in a read-only map value. It also checks that this
pointer is followed by a zero character before the end of the map value.

We have a usecase where we want to audit symbol names (if available) in
callback registration hooks. (ex: fentry/nf_register_net_hook)
A few months back, I proposed a bpf_kallsyms_lookup series but it was
decided in the reviews that a more generic helper, bpf_snprintf, would
be more useful.

The MAC device name can now be set within DTS file instead of always
being "ethX". This is helpful for DSA to clearly label the DSA master
device and distinguish it from DSA slave ports.
For example, some devices, such as the Ubiquiti EdgeRouter X, may have
ports labeled ethX. Labeling the master
Add support for specifying GMAC label via DTS. Useful when it is desired
to use a master DSA interface name that is different from the "eth%d"
pattern.
v2:
- Use alloc_netdev instead of alloc_etherdev followed by rename
