drbd: Remove the open-coded page pool

2025-08-11T13:54:27+00:00

If the network stack keeps a reference for too long, DRBD keeps references on a higher number of pages as a consequence. Fix all that by no longer relying on page reference counts dropping to an expected value. Instead, DRBD gives up its reference and lets the system handle everything else. While at it, remove the open-coded custom page pool mechanism and use the page_pool included in the kernel.

drbd: pass drbd_peer_device to __req_mod

In preparation to support multiple connections, we need to know which one we need to modify the request state for. Originally-from: Lars Ellenberg Signed-off-by: Christoph Böhmwalder Link: https://lore.kernel.org/r/20230330102744.2128122-2-christoph.boehmwalder@linbit.com Signed-off-by: Jens Axboe

drbd: Add peer device parameter to whole-bitmap I/O handlers

2023-04-02T02:27:55+00:00

Pass a peer device parameter through the bitmap I/O functions to the I/O handlers. In after_state_ch(), set that parameter when queuing the drbd_send_bitmap operation so that this operation knows where to send the bitmap.

drbd: introduce drbd_ratelimit()

2022-12-01T18:33:49+00:00

Use call site specific ratelimit instead of one single static global. Also ratelimit ASSERTION messages generated by expect().

drbd: use consistent license

2022-11-23T02:38:39+00:00

DRBD currently has a mix of GPL-2.0 and GPL-2.0-or-later SPDX license identifiers. We have decided to stick with GPL 2.0 only, so consistently use that identifier.

drbd: Store op in drbd_peer_request

2022-11-09T19:40:36+00:00

(Sort of) cherry-picked from the out-of-tree drbd9 branch. Original commit message by Joel Colledge: This simplifies drbd_submit_peer_request by removing most of the arguments. It also makes the treatment of the op better aligned with that in struct bio. Determine fault_type dynamically using information which is already available instead of passing it in as a parameter. Note: The opf in receive_rs_deallocated was changed from REQ_OP_WRITE_ZEROES to REQ_OP_DISCARD. This was required in the out-of-tree module, and does not matter in-tree. The opf is ignored anyway in drbd_submit_peer_request, since the discard/zero-out is decided by the EE_TRIM flag.

Combine the drbd_submit_peer_request() 'op' and 'op_flags' arguments into a single argument. This patch does not change any functionality.
