Because of patch[1] the graft behaviour changed
So the command:
tcq replace parent 100:1 handle 204:
Is no longer valid and will not delete 100:4 added by command:
tcq replace parent 100:4 handle 204: pfifo_fast
So to maintain the original behaviour, this patch manually deletes 100:4
and grafts 100:1
Note: This change will also work fine without [1]

[FAIL] Tests of the full disconnection have failed
Time: 2 seconds
The root cause is actually in the user-space bits: the test program
currently disconnects as soon as all the pending data has been spooled,
generating an FASTCLOSE. If such option reaches the peer before the
latter has reached the closed status, the msk socket will report an
error to the user-space, as per protocol specification, causing the
above failure.
Address the issue explicitly waiting for all the relevant sockets to
reach a closed status before performing the disconnect.

After commit b1f202060a ("mm: remap unused subpages to shared zeropage
when splitting isolated thp"), cow test cases involving swapping out THPs
via madvise(MADV_PAGEOUT) started to be skipped due to the subsequent
check via pagemap determining that the memory was not actually swapped
out. Logs similar to this were emitted:
...
# [RUN] Basic COW after fork() ... with swapped-out, PTE-mapped THP (16 kB)
ok 2 # SKIP MADV_PAGEOUT did not work, is swap enabled?
# [RUN] Basic COW after fork() ... with single PTE of swapped-out THP (16 kB)
ok 3 # SKIP MADV_PAGEOUT did not work, is swap enabled?
# [RUN] Basic COW after fork() ... with swapped-out, PTE-mapped THP (32 kB)
ok 4 # SKIP MADV_PAGEOUT did not work, is swap enabled?
...
The commit in question introduces the behaviour of scanning THPs and if
their content is predominantly zero, it splits them and replaces the pages
which are wholly zero with the zero page. These cow test cases were
getting caught up in this.
So let's avoid that by filling the contents of all allocated memory with
a non-zero value. With this in place, the tests are passing again.

"The largest part here is for KVM/PPC, where a NULL pointer dereference
was introduced in the 6.13 merge window and is now fixed.
There's some "holiday-induced lateness", as the s390 submaintainer put
it, but otherwise things looks fine.

re-enabled

The dsp_local_on selftest expects the scheduler to fail by trying to
schedule an e.g. CPU-affine task to the wrong CPU. However, this isn't
guaranteed to happen in the 1 second window that the test is running.
Besides, it's odd to have this particular exception path tested when there
are no other tests that verify that the interface is working at all - e.g.
the test would pass if dsp_local_on interface is completely broken and fails
on any attempt.
Flip the test so that it verifies that the feature works. While at it, fix a
typo in the info message.
