Next, as the probing-board is not tied to any topology file, it shall

ata: libata-eh: Fix link state check for IDE/PATA ports
Commit 4371fe1ba400 ("ata: libata-eh: Avoid unnecessary resets when

ata_eh_revalidate_and_attach() with the new function
ata_eh_link_established() which relaxes the checks on a device link
state to account for low power mode transitions. However, this change
assumed that the device port has a valid scr_read method to obtain the
SStatus register for the port. This is not always the case, especially
with older IDE/PATA adapters (e.g. PATA/IDE devices emulated with QEMU).
For such adapter, ata_eh_link_established() will always return false,
causing ata_eh_revalidate_and_attach() to go into its error path and
ultimately to the device being disabled.
Avoid this by restoring the previous behavior, which is to assume that
the link is online if reading the port SStatus register fails.
While at it, also fix the spelling of SStatus in the comment describing
the function ata_eh_link_established().

smb: client: remove redundant lstrp update in negotiate protocol
Commit 34331d7beed7 ("smb: client: fix first command failure during
re-negotiation") addressed a race condition by updating lstrp before
entering negotiate state. However, this approach may have some unintended
side effects.
The lstrp field is documented as "when we got last response from this
server", and updating it before actually receiving a server response
could potentially affect other mechanisms that rely on this timestamp.
For example, the SMB echo detection logic also uses lstrp as a reference
point. In scenarios with frequent user operations during reconnect states,
the repeated calls to cifs_negotiate_protocol() might continuously
update lstrp, which could interfere with the echo detection timing.
Additionally, commit 266b5d02e14f ("smb: client: fix race condition in
negotiate timeout by using more precise timing") introduced a dedicated
neg_start field specifically for tracking negotiate start time. This
provides a more precise solution for the original race condition while
preserving the intended semantics of lstrp.
Since the race condition is now properly handled by the neg_start
mechanism, the lstrp update in cifs_negotiate_protocol() is no longer
necessary and can be safely removed.

smb: client: fix mid_q_entry memleak leak with per-mid locking
This is step 4/4 of a patch series to fix mid_q_entry memory leaks
caused by race conditions in callback execution.
In compound_send_recv(), when wait_for_response() is interrupted by
signals, the code attempts to cancel pending requests by changing
their callbacks to cifs_cancelled_callback. However, there's a race
condition between signal interruption and network response processing
that causes both mid_q_entry and server buffer leaks:
```
User foreground process cifsd
cifs_readdir
open_cached_dir
cifs_send_recv
compound_send_recv
smb2_setup_request
smb2_mid_entry_alloc
smb2_get_mid_entry
smb2_mid_entry_alloc
mempool_alloc // alloc mid
kref_init(&temp->refcount); // refcount = 1
mid[0]->callback = cifs_compound_callback;
mid[1]->callback = cifs_compound_last_callback;
smb_send_rqst
rc = wait_for_response
wait_event_state TASK_KILLABLE
cifs_demultiplex_thread
allocate_buffers
server->bigbuf = cifs_buf_get()
standard_receive3
->find_mid()
smb2_find_mid
__smb2_find_mid
kref_get(&mid->refcount) // +1
cifs_handle_standard
handle_mid
/* bigbuf will also leak */
mid->resp_buf = server->bigbuf
server->bigbuf = NULL;
dequeue_mid
/* in for loop */
mids[0]->callback
cifs_compound_callback
/* Signal interrupts wait: rc = -ERESTARTSYS */
/* if (... || midQ[i]->mid_state == MID_RESPONSE_RECEIVED) *?
midQ[0]->callback = cifs_cancelled_callback;
cancelled_mid[i] = true;
/* The change comes too late */
mid->mid_state = MID_RESPONSE_READY
release_mid // -1
/* cancelled_mid[i] == true causes mid won't be released
in compound_send_recv cleanup */
/* cifs_cancelled_callback won't executed to release mid */
```
The root cause is that there's a race between callback assignment and
execution.
Fix this by introducing per-mid locking:
- Add spinlock_t mid_lock to struct mid_q_entry
- Add mid_execute_callback() for atomic callback execution
- Use mid_lock in cancellation paths to ensure atomicity
This ensures that either the original callback or the cancellation
callback executes atomically, preventing reference count leaks when
requests are interrupted by signals.

io_uring/io-wq: add check free worker before create new worker
After commit 0b2b066f8a85 ("io_uring/io-wq: only create a new worker
if it can make progress"), in our produce environment, we still
observe that part of io_worker threads keeps creating and destroying.
After analysis, it was confirmed that this was due to a more complex
scenario involving a large number of fsync operations, which can be
abstracted as frequent write + fsync operations on multiple files in
a single uring instance. Since write is a hash operation while fsync
is not, and fsync is likely to be suspended during execution, the
action of checking the hash value in
io_wqe_dec_running cannot handle such scenarios.
Similarly, if hash-based work and non-hash-based work are sent at the
same time, similar issues are likely to occur.
Returning to the starting point of the issue, when a new work
arrives, io_wq_enqueue may wake up free worker A, while
io_wq_dec_running may create worker B. Ultimately, only one of A and
B can obtain and process the task, leaving the other in an idle
state. In the end, the issue is caused by inconsistent logic in the
checks performed by io_wq_enqueue and io_wq_dec_running.
Therefore, the problem can be resolved by checking for available
workers in io_wq_dec_running.

block: restore default wbt enablement
The commit 245618f8e45f ("block: protect wbt_lat_usec using
q->elevator_lock") protected wbt_enable_default() with
q->elevator_lock; however, it also placed wbt_enable_default()
before blk_queue_flag_set(QUEUE_FLAG_REGISTERED, q);, resulting
in wbt failing to be enabled.
Moreover, the protection of wbt_enable_default() by q->elevator_lock
was removed in commit 78c271344b6f ("block: move wbt_enable_default()
out of queue freezing from sched ->exit()"), so we can directly fix
this issue by placing wbt_enable_default() after
blk_queue_flag_set(QUEUE_FLAG_REGISTERED, q);.
Additionally, this issue also causes the inability to read the
wbt_lat_usec file, and the scenario is as follows:
