Subject: [PATCH for-rc 1/2] RDMA/bnxt_re: Use kvzalloc for QP table allocation
Date: Tue, 13 Oct 2026 07:04:26 -0700	[thread overview]
Message-ID: <20261013140427.256612-2-selvin.xavier@broadcom.com> (raw)
In-Reply-To: <20261013140427.256612-1-selvin.xavier@broadcom.com>

From: Abhishek Mohapatra <abhishek.mohapatra@broadcom.com>

The QP table size depends on the firmware reported max_qp, so it can
be large and a physically contiguous kzalloc may fail. Use kvzalloc_objs()
and free it with kvfree().

Fixes: 82f1f575aa13 ("RDMA/bnxt_re: Fix allocation of QP table")
