SRU Justification
[Impact]
- * Request from Microsoft to
+ * Request from Microsoft to backport a couple of MANA patches to provide
+ better memory allocation around fragmented memory.
[Fix]
- * SAUCE patch to revert commit
+ * Resolute:
+ - Clean cherry-pick of linux-next patches:
+ - 3af0820c878e "net: mana: Use kvmalloc for large RX queue and buffer
allocations"
+ - d07efe5a6e64: "net: mana: Use per-queue allocation for tx_qp to reduce
allocation size"
+ * Questing/Noble/Jammy:
+ - Semi-straightforward backport of linux-next patches:
+ - 3af0820c878e "net: mana: Use kvmalloc for large RX queue and buffer
allocations"
+ - d07efe5a6e64: "net: mana: Use per-queue allocation for tx_qp to reduce
allocation size"
[Test Plan]
* Compile tested
* Boot tested
* Microsoft tested
[Regression potential]
- * Reverting functionality back to previous release, so regression risk
- not likely
+ * Patches isolated to MANA specifically. Issues in memory allocation
+ could cause kernel panics, so these should be tested substantially.
