I just dropped the second part of the iopoll changes, so it's back to just this one: https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux.git/commit/?h=for-7.0/io_uring&id=3c7d76d6128a0fef68e6540754bf85a44a29bb59 I didn't have an immediately good idea for solving it without doing more locking and/or synchronization, and I wasn't convinced it was worth it. I'll ponder it some more next week and pick it back up. -- Jens Axboe From - Sat Jan 10 10:02:35 2026 X-Mozilla-Status: 0001 X-Mozilla-Status2: 00000000 Return-Path: Delivered-To: hi@josie.lol Received: from witcher.mxrouting.net by witcher.mxrouting.net with LMTP id 8PU9IoiVYWm9+hYAYBR5ng (envelope-from ) for ;

I.e. the common get/set operations always worked in atomic mode, but now complain. See for example: https://lore.kernel.org/all/20260108-media-synopsys-hdmirx-fix-gpio-canslee= p-v1-1-3570518d8bab@kernel.org/ It's not a big issue for the hdmirx driver specifically, but I wonder how many more (less often tested) rockchip drivers use GPIOs from their IRQ handler. Considering setting or getting the GPIO from atomic context is much more common than changing the direction - is there some way to describe the sleep behavior in a more specific way in the GPIO controller?

The size of vif driver data is set by each WiFi driver as needed. The RSI911x driver does not set vif driver data size, no trailing space for vif driver data is therefore allocated past struct ieee80211_vif . The RSI911x driver does however use the vif driver data to store its vif driver data structure "struct vif_priv". An access to vif->drv_priv leads to access out of struct ieee80211_vif bounds and corruption of some memory. In case of the failure observed locally, rsi_mac80211_add_interface() would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv; vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member struct list_head new_flows . The flow = list_first_entry(head, struct fq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogus address, which when accessed causes a crash. The trigger is very simple, boot the machine with init=/bin/sh , mount devtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1", "ip link set wlan0 down" and the crash occurs. Fix this by setting the correct size of vif driver data, which is the size of "struct vif_priv", so that memory is allocated and the driver can store its driver data in it, instead of corrupting memory around it.

As a result, if VMSAVE/VMLOAD is executed by an L2 guest and is not intercepted by L1, KVM will mistakenly use vmcb02. Always use vmcb01 instead of the current VMCB.

So I think we need a softdep between ohci-platform/uhci-platform and ehci-platform, which is similar to the PCI case. > > There are other issues involving companion controllers, connected with > hibernation. You should take a look at commit 6d19c009cc78 ("USB: > implement non-tree resume ordering constraints for PCI host > controllers"), which was later modified by commit 05768918b9a1 ("USB: > improve port transitions when EHCI starts up") and a few others. > > Also, read through the current code in hcd-pci.c (for_each_companion(), > ehci_pre_add(), ehci_post_add(), non_ehci_add(), ehci_remove(), and > ehci_wait_for_companions()).
