The NetDIM library, currently leveraged by an array of NICs, delivers
excellent acceleration benefits. Nevertheless, NICs vary significantly
in their dim profile list prerequisites.
Specifically, virtio-net backends may present diverse sw or hw device
implementation, making a one-size-fits-all parameter list impractical.
On Alibaba Cloud, the virtio DPU's performance under the default DIM
profile falls short of expectations, partly due to a mismatch in
parameter configuration.
I also noticed that ice/idpf/ena and other NICs have customized
profilelist or placed some restrictions on dim capabilities.
Motivated by this, I tried adding new params for "ethtool -C" that provides
a per-device control to modify and access a device's interrupt parameters.
Usage
========
The target NIC is named ethx.
Assume that ethx only declares support for rx profile setting
(with DIM_PROFILE_RX flag set in profile_flags) and supports modification
of usec and pkt fields.
1. Query the currently customized list of the device
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 256, .comps = n/a,},
{.usec = 8, .pkts = 256, .comps = n/a,},
{.usec = 64, .pkts = 256, .comps = n/a,},
{.usec = 128, .pkts = 256, .comps = n/a,},
{.usec = 256, .pkts = 256, .comps = n/a,}
tx-profile: n/a
2. Tune
$ ethtool -C ethx rx-profile 1,1,n_2,n,n_3,3,n_4,4,n_n,5,n
"n" means do not modify this field.
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 1, .comps = n/a,},
{.usec = 2, .pkts = 256, .comps = n/a,},
{.usec = 3, .pkts = 3, .comps = n/a,},
{.usec = 4, .pkts = 4, .comps = n/a,},
{.usec = 256, .pkts = 5, .comps = n/a,}
tx-profile: n/a
3. Hint
If the device does not support some type of customized dim profiles,
the corresponding "n/a" will display.
If the "n/a" field is being modified, -EOPNOTSUPP will be reported.

DIMLIB's capabilities are supplied by the dim, net_dim, and
rdma_dim objects, and dim's interfaces solely act as a base for
net_dim and rdma_dim and are not explicitly used anywhere else.
rdma_dim is utilized by the infiniband driver, while net_dim
is for network devices, excluding the soc/fsl driver.
In this patch, net_dim relies on some NET's interfaces, thus
DIMLIB needs to explicitly depend on the NET Kconfig.
The soc/fsl driver uses the functions provided by net_dim, so
it also needs to depend on NET.

Worst case scenario of plist_add() happens when the priority of the
inserted plist_node is going to be the largest after the insertion is
done. The cost is going to be more significant when the original plist is
longer, because the iterator is going to traverse the whole plist to find
the correct position to insert the new node.
The situation can be avoided by using a reverse iterator at the same time,
doing so the maximum possible number of iteration is going to shrink from
N to N/2.
The proposed change of plist_add pasts the test in lib/plist.c to validate
its correctness, also add the worst case scenario test for plist_add() in
plist_test().
The worst case test are tested with the size of test_data and test_node
growing from 200 to 1000. The result are showned in the following table,
in which we can observed that the proposed change of plist_add performs
better than the original version, and the difference between these two
implementations are more significant with the size of N growing.
The random case test [1], and best case test [2] are also provided, with
result showing the proposed change performs slightly better in random case
test while the original implementation performs slightly better in best
case test, while the difference in both test are minor, we can see them as
even in those two situations.

There exists an iteration over a plist in plist_check_list(), and memory
dependency exists between variables "prev", "next" and "prev->next". As
plist is used in the scheduling subsystem, we should guarantee the memory
ordering between multiple processors.
Using macro "WRITE_ONCE()" can help us to ensure the memory ordering as
it was stated in "Documentation/memory-barriers.txt".

Interrupt disable/enable trips are quite expensive on x86-64 compared to a
mere cmpxchg (note: no lock prefix!) and percpu counters are used quite
often.
With this change I get a bump of 1% ops/s for negative path lookups,
plugged into will-it-scale:
void testcase(unsigned long long *iterations, unsigned long nr)
{
while (1) {
int fd = open("/tmp/nonexistent", O_RDONLY);
assert(fd == -1);
(*iterations)++;
}
}
The win would be higher if it was not for other slowdowns, but one has
to start somewhere.

The addition of an if statement in lib/sort to handle the final unsorted 2
or 3 elements is not covered by existing test cases, leading to incomplete
test coverage. To ensure comprehensive testing and maintain 100% code
coverage, add a new testcase for scenarios where the if statement is
triggered.
Since the if statement is only triggered when the array length is odd and
the first element is greater than the second element, a testcase is
created using an array length of TEST_LEN - 1 and a suitable random seed
to maintain full code coverage.

After building the heap, the code continuously pops two elements from the
heap until only 2 or 3 elements remain, at which point it switches back to
a regular heapsort with one element popped at a time. However, to handle
the final 2 or 3 elements, an additional else-if statement in the while
loop was introduced, potentially increasing branch misses. Moreover, when
there are only 2 or 3 elements left, continuing with regular heapify
operations is unnecessary as these cases are simple enough to be handled
with a single comparison and 1 or 2 swaps outside the while loop.
Eliminating the additional else-if statement and directly managing cases
involving 2 or 3 elements outside the loop reduces unnecessary conditional
branches resulting from the numerous loops and conditionals in heapify.
This optimization maintains consistent numbers of comparisons and swaps
for arrays with even lengths while reducing swaps and comparisons for
arrays with odd lengths from 2.5 swaps and 1 comparison to 1.5 swaps and 1
comparison.

The existing comment in lib/sort refers to glibc qsort() using quicksort.
However, glibc qsort() no longer uses quicksort; it now uses mergesort and
falls back to heapsort if memory allocation for mergesort fails. This
makes the comment outdated and incorrect.
Update the comment to refer to quicksort in general rather than glibc's
implementation to provide accurate information about the comparisons and
trade-offs without implying an outdated implementation.

descriptions regarding glibc qsort() and removes the unused pr_fmt macro.
This patch (of 4):
The pr_fmt macro is defined but not used in lib/sort.c. Since there are
no pr_* functions printing any messages, the pr_fmt macro is redundant and
can be safely removed.

"Lots of (mostly boring) fixes for syzbot bugs and rare(r) CI bugs.
The LRU_TIME_BITS fix was slightly more involved; we only have 48 bits
for the LRU position (we would prefer 64), so wraparound is possible
for the cached data LRUs on a filesystem that has done sufficient
(petabytes) reads; this is now handled.
One notable user reported bugfix, where we were forgetting to
correctly set the bucket data type, which should have been
BCH_DATA_need_gc_gens instead of BCH_DATA_free; this was causing us to
go emergency read-only on a filesystem that had seen heavy enough use
to see bucket gen wraparoud.
We're now starting to fix simple (safe) errors without requiring user
intervention - i.e. a small incremental step towards full self
healing.
This is currently limited to just certain allocation information
counters, and the error is still logged in the superblock; see that

Hardcoding the number of CPUs at compile time does improve code
generation, but if you get it wrong the result will be confusion.
We already limited this earlier to only "experts" (see commit
fe5759d5bf "cpumask: limit visibility of FORCE_NR_CPUS"), but with
distro kernel configs often having EXPERT enabled, that turns out to not
be much of a limit.
To quote the philosophers at Disney: "Everyone can be an expert. And
when everyone's an expert, no one will be".
There's a runtime warning if you then set nr_cpus to anything but the
forced number, but apparently that can be ignored too [1] and by then
it's pretty much too late anyway.
If we had some real way to limit this to "embedded only", maybe it would
be worth it, but let's see if anybody even notices that the option is
gone. We need to simplify kernel configuration anyway.

For tests that need to allocate using vm_mmap() (e.g. usercopy and
execve), provide the interface to have the allocation tracked by KUnit
itself. This requires bringing up a placeholder userspace mm.
This combines my earlier attempt at this with Mark Rutland's version[1].
Normally alloc_mm() and arch_pick_mmap_layout() aren't exported for
modules, so export these only for KUnit testing.
