  "message": "providers/mana: skip SQ rollback region when pow2 SQ is supported\n\nThe requester SQ of an RC QP carries a trailing rollback shared-memory\nblock so that the rollback point can be recovered from software. When\nthe adapter accepts a power-of-two send queue, the rollback point is\nderived from the WQE size alone and the block is not needed.\n\nThe kernel advertises this with MANA_IB_UCNTX_RC_SQ_POW2_SUPPORT. Skip\nthe extra allocation and the per-post and per-completion offset updates\nwhen it is set together with MANA_IB_UCNTX_RC_EXT_SUPPORT. Gate the\nbehaviour on a new per-QP rollback_sq flag so that QPs running on older\nkernels keep the legacy layout.\n\nSigned-off-by: Snehal Sanghvi \u003csnsanghvi@microsoft.com\u003e\nReviewed-by: Konstantin Taranov \u003ckotaranov@microsoft.com\u003e\n",
