**YES** This commit should be backported to stable kernel trees. ##
Extensive Analysis ### Code Changes Analysis The commit adds **25 new
PCI ID entries** to the smartpqi driver's `pqi_pci_id_table[]` in
`drivers/scsi/smartpqi/smartpqi_init.c`. All changes follow the
identical pattern: ```c { PCI_DEVICE_SUB(PCI_VENDOR_ID_ADAPTEC2, 0x028f,
subvendor_id, subdevice_id) }, ``` **Key technical characteristics:** -
**Same device ID (0x028f)**: All entries use the identical base device
ID, indicating the same underlying Microchip chipset - **Only
vendor/subdevice variations**: Changes only affect which OEM hardware
variants the driver will claim - **Pure table additions**: No functional
code modifications, algorithm changes, or new logic paths - **Maintains
table structure**: Preserves existing entries and the critical
`PCI_ANY_ID` wildcard terminator ### Why This Merits Backporting **1.
Explicit Stable Policy Compliance** The Linux stable kernel rules at
`/home/sasha/linux/Documentation/process/stable-kernel-rules.rst:15`
explicitly state: *"It must either fix a real bug that bothers people or
just add a device ID."* This commit directly falls under the "device ID
addition" category that stable policy encourages. **2. Hardware Support
Without Risk** - **Zero functional impact**: The smartpqi driver uses
unified hardware detection and initialization regardless of PCI ID -
**No existing hardware affected**: New IDs only enable support for
previously unsupported hardware - **Same code paths**: All controllers
use identical probe/initialization functions (`pqi_pci_probe`) -
**Runtime capability detection**: Controller features are discovered at
runtime, not determined by PCI IDs **3. Strong Historical Precedent**
Recent smartpqi PCI ID commits show systematic stable backporting: -
**dbc39b84540f** (Aug 2024) → backported to v6.11.3-v6.11.11 -
**0e21e73384d3** (July 2024) → backported to v6.11.3-v6.11.11 - Pattern
shows stable maintainers routinely backport these changes **4. User
Impact Considerations** - **Enterprise hardware support**: Enables
critical storage controller support for servers already in production -
**OEM ecosystem**: Supports Lenovo ThinkSystem, Ramaxel, Alibaba,
Inspur, Delta, Cloudnine, and Hurraydata controllers - **No regression
risk**: Cannot break existing functionality since it only adds new
hardware recognition **5. Technical Safety Assessment** The smartpqi
driver architecture makes PCI ID additions exceptionally safe: -
**Unified PQI interface**: All hardware uses the same Physical Queue
Interface standard - **Common initialization**: Single code path handles
all variants - **Wildcard fallback**: Existing `PCI_ANY_ID` entry
provides compatibility safety net - **Module parameter control**:
`disable_device_id_wildcards` allows administrators to control behavior
### Comparison with Historical Examples The provided reference commits
confirm this assessment: - **Similar Commit #1 & #2**: Marked "YES" for
backporting, involve identical PCI ID table additions - **Similar Commit
#3, #4, #5**: Marked "NO" but appear to be earlier commits from
different timeframes with different maintainer practices ### Risk
Analysis **Minimal Risk Profile:** - **No code logic changes**: Pure
data table modification - **Isolated impact scope**: Only affects
hardware device matching - **Reversible**: Changes can be easily
reverted if issues arise - **Well-tested pattern**: Follows established
commit pattern with extensive reviewer approval **Conclusion:** This
commit represents exactly the type of low-risk hardware support addition
that stable kernel policy explicitly encourages for backporting. The
combination of zero functional risk, clear user benefit, strong
historical precedent, and explicit stable policy support makes this an
ideal candidate for stable tree inclusion.
