dt-bindings: net: fec: add pps channel property

2024-12-27T12:58:58Z

commit 1aa772be0444a2bd06957f6d31865e80e6ae4244 upstream. Add fsl,pps-channel property to select where to connect the PPS signal. This depends on the internal SoC routing and on the board, for example on the i.MX8 SoC it can be connected to an external pin (using channel 1) or to internal eDMA as DMA request (channel 0).

net: fec: make PPS channel configurable

2024-12-27T12:58:57Z

commit 566c2d83887f0570056833102adc5b88e681b0c7 upstream. Depending on the SoC where the FEC is integrated into the PPS channel might be routed to different timer instances. Make this configurable from the devicetree. When the related DT property is not present fallback to the previous default and use channel 0.

io_uring/rw: avoid punting to io-wq directly

2024-12-27T12:58:57Z

Commit 6e6b8c62120a22acd8cb759304e4cd2e3215d488 upstream. kiocb_done() should care to specifically redirecting requests to io-wq. Remove the hopping to tw to then queue an io-wq, return -EAGAIN and let the core code io_uring handle offloading.

io_uring/rw: treat -EOPNOTSUPP for IOCB_NOWAIT like -EAGAIN

2024-12-27T12:58:57Z

Commit c0a9d496e0fece67db777bd48550376cf2960c47 upstream. Some file systems, ocfs2 in this case, will return -EOPNOTSUPP for an IOCB_NOWAIT read/write attempt. While this can be argued to be correct, the usual return value for something that requires blocking issue is -EAGAIN. A refactoring io_uring commit dropped calling kiocb_done() for negative return values, which is otherwise where we already do that transformation. To ensure we catch it in both spots, check it in __io_read() itself as well.

Commit a08d195b586a217d76b42062f88f375a3eedda4d upstream. Add __io_read() which does the grunt of the work, leaving the completion side to the new io_read(). No functional changes in this patch.

epoll: Add synchronous wakeup support for ep_poll_callback

2024-12-27T12:58:57Z

commit 900bbaae67e980945dec74d36f8afe0de7556d5a upstream. Now, the epoll only use wake_up() interface to wake up task. However, sometimes, there are epoll users which want to use the synchronous wakeup flag to hint the scheduler, such as Android binder driver. So add a wake_up_sync() define, and use the wake_up_sync() when the sync is true in ep_poll_callback().

ceph: fix memory leaks in __ceph_sync_read()

2024-12-27T12:58:57Z

commit d6fd6f8280f0257ba93f16900a0d3d3912f32c79 upstream. In two `break` statements, the call to ceph_release_page_vector() was missing, leaking the allocation from ceph_alloc_page_vector(). Instead of adding the missing ceph_release_page_vector() calls, the Ceph maintainers preferred to transfer page ownership to the `ceph_osd_request` by passing `own_pages=true` to osd_req_op_extent_osd_data_pages(). This requires postponing the ceph_osdc_put_request() call until after the block that accesses the `pages`.
