Subject: [PATCH v2 0/2] RDMA/rw: Fix MR pool exhaustion in bvec RDMA READ path
Date: Thu, 12 Mar 2026 09:40:06 -0400 [thread overview]
Message-ID: <20260312134008.7387-1-cel@kernel.org> (raw)
From: Chuck Lever <chuck.lever@oracle.com>
This series now carries the original fix with review comments
addressed, and a proposal for using contiguous pages for RDMA Read
sink buffers in svcrdma. IMO the fix patch should go into 7.0-rc,
and the RDMA Read behavior change can wait for the next merge
window.
Base commit: v7.0-rc3
---
Changes since v1:
- Clarify code comments
- Allocate contiguous pages for RDMA Read sink buffers

svcrdma: Use contiguous pages for RDMA Read sink buffers
