The call to invalidate_inode_pages2_range() in __iomap_dio_rw() may fail, in which case -ENOTBLK is returned and this error code is propagated back to user space trhough iomap_dio_rw() -> zonefs_file_dio_write() return chain. This error code is fairly obscure and may confuse the user. Avoid this and be consistent with the behavior of zonefs_file_dio_append() for similar invalidate_inode_pages2_range() errors by returning -EBUSY to user space when iomap_dio_rw() returns -ENOTBLK.

When a direct append write is executed, the append offset may correspond to the last page of a sequential file inode which might have been cached already by buffered reads, page faults with mmap-read or non-direct readahead. To ensure that the on-disk and cached data is consistant for such last cached page, make sure to always invalidate it in zonefs_file_dio_append(). If the invalidation fails, return -EBUSY to userspace to differentiate from IO errors. This invalidation will always be a no-op when the FS block size (device zone write granularity) is equal to the page size (e.g. 4K). Reported-by:

8b/10b encoding needs to add 3% fec overhead into the pbn. In the Synapcis Cascaded MST hub, the first stage MST branch device needs the information to determine the timeslot count for the second stage MST branch device. Missing this overhead will leads to insufficient timeslot allocation. Cc: stable@vger.kernel.org Cc: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by:

The drm_buddy_test KUnit tests verify that returned blocks have sizes which are powers of two using is_power_of_2(). However, is_power_of_2() operations on a 'long', but the block size is a u64. So on systems where long is 32-bit, this can sometimes fail even on correctly sized blocks. This only reproduces randomly, as the parameters passed to the buddy allocator in this test are random. The seed 0xb2e06022 reproduced it fine here. For now, just hardcode an is_power_of_2() implementation using x & (x - 1). Signed-off-by:

The drm buddy allocator tests were broken on 32-bit systems, as rounddown_pow_of_two() takes a long, and the buddy allocator handles 64-bit sizes even on 32-bit systems. This can be reproduced with the drm_buddy_allocator KUnit tests on i386: ./tools/testing/kunit/kunit.py run --arch i386 \ --kunitconfig ./drivers/gpu/drm/tests drm_buddy (It results in kernel BUG_ON() when too many blocks are created, due to the block size being too small.) This was independently uncovered (and fixed) by Luís Mendes, whose patch added a new u64 variant of rounddown_pow_of_two(). This version instead recalculates the size based on the order. Reported-by:

The nouveau code used to call drm_fb_helper_initial_config() from nouveau_fbcon_init() before calling drm_dev_register(). This would probe all connectors so that drm_connector->status could be used during backlight registration which runs from nouveau_connector_late_register(). After commit 4a16dd9d ("drm/nouveau/kms: switch to drm fbdev helpers") the fbdev emulation code, which now is a drm-client, can only run after drm_dev_register(). So during backlight registration the connectors are not probed yet and the drm_connector->status == connected check in nv50_backlight_init() would now always fail. Replace the drm_connector->status == connected check with a drm_helper_probe_detect() == connected check to fix nv_backlight no longer getting registered because of this.

snd_card_ymfpci_remove() was removed in commit c6e6bb5e ("ALSA: ymfpci: Allocate resources with device-managed APIs"), but the call to snd_card_new() was not replaced with snd_devm_card_new(). Since there was no longer a call to snd_card_free, unloading the module would eventually result in Oops: [697561.532887] BUG: unable to handle page fault for address: ffffffffc0924480 [697561.532893] #PF: supervisor read access in kernel mode [697561.532896] #PF: error_code(0x0000) - not-present page [697561.532899] PGD ae1e15067 P4D ae1e15067 PUD ae1e17067 PMD 11a8f5067 PTE 0 [697561.532905] Oops: 0000 [#1] PREEMPT SMP NOPTI [697561.532909] CPU: 21 PID: 5080 Comm: wireplumber Tainted: G W OE 6.2.7 #1 [697561.532914] Hardware name: System manufacturer System Product Name/TUF GAMING X570-PLUS, BIOS 4408 10/28/2022 [697561.532916] RIP: 0010:try_module_get.part.0+0x1a/0xe0 [697561.532924] Code: 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 00 00 55 48 89 e5 41 55 41 54 49 89 fc bf 01 00 00 00 e8 56 3c f8 ff <41> 83 3c 24 02 0f 84 96 00 00 00 41 8b 84 24 30 03 00 00 85 c0 0f [697561.532927] RSP: 0018:ffffbe9b858c3bd8 EFLAGS: 00010246 [697561.532930] RAX: ffff9815d14f1900 RBX: ffff9815c14e6000 RCX: 0000000000000000 [697561.532933] RDX: 0000000000000000 RSI: ffffffffc055092c RDI: ffffffffb3778c1a [697561.532935] RBP: ffffbe9b858c3be8 R08: 0000000000000040 R09: ffff981a1a741380 [697561.532937] R10: ffffbe9b858c3c80 R11: 00000009d56533a6 R12: ffffffffc0924480 [697561.532939] R13: ffff9823439d8500 R14: 0000000000000025 R15: ffff9815cd109f80 [697561.532942] FS: 00007f13084f1f80(0000) GS:ffff9824aef40000(0000) knlGS:0000000000000000 [697561.532945] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [697561.532947] CR2: ffffffffc0924480 CR3: 0000000145344000 CR4: 0000000000350ee0 [697561.532949] Call Trace: [697561.532951] <TASK> [697561.532955] try_module_get+0x13/0x30 [697561.532960] snd_ctl_open+0x61/0x1c0 [snd] [697561.532976] snd_open+0xb4/0x1e0 [snd] [697561.532989] chrdev_open+0xc7/0x240 [697561.532995] ? fsnotify_perm.part.0+0x6e/0x160 [697561.533000] ? __pfx_chrdev_open+0x10/0x10 [697561.533005] do_dentry_open+0x169/0x440 [697561.533009] vfs_open+0x2d/0x40 [697561.533012] path_openat+0xa9d/0x10d0 [697561.533017] ? debug_smp_processor_id+0x17/0x20 [697561.533022] ? trigger_load_balance+0x65/0x370 [697561.533026] do_filp_open+0xb2/0x160 [697561.533032] ? _raw_spin_unlock+0x19/0x40 [697561.533036] ? alloc_fd+0xa9/0x190 [697561.533040] do_sys_openat2+0x9f/0x160 [697561.533044] __x64_sys_openat+0x55/0x90 [697561.533048] do_syscall_64+0x3b/0x90 [697561.533052] entry_SYSCALL_64_after_hwframe+0x72/0xdc [697561.533056] RIP: 0033:0x7f1308a40db4 [697561.533059] Code: 24 20 eb 8f 66 90 44 89 54 24 0c e8 46 68 f8 ff 44 8b 54 24 0c 44 89 e2 48 89 ee 41 89 c0 bf 9c ff ff ff b8 01 01 00 00 0f 05 <48> 3d 00 f0 ff ff 77 32 44 89 c7 89 44 24 0c e8 78 68 f8 ff 8b 44 [697561.533062] RSP: 002b:00007ffcce664450 EFLAGS: 00000293 ORIG_RAX: 0000000000000101 [697561.533066] RAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007f1308a40db4 [697561.533068] RDX: 0000000000080000 RSI: 00007ffcce664690 RDI: 00000000ffffff9c [697561.533070] RBP: 00007ffcce664690 R08: 0000000000000000 R09: 0000000000000012 [697561.533072] R10: 0000000000000000 R11: 0000000000000293 R12: 0000000000080000 [697561.533074] R13: 00007f13054b069b R14: 0000565209f83200 R15: 0000000000000000 [697561.533078] </TASK> Fixes: c6e6bb5e ("ALSA: ymfpci: Allocate resources with device-managed APIs") Signed-off-by:

The device release callback function invoked to release the matrix device uses the dev_get_drvdata(device *dev) function to retrieve the pointer to the vfio_matrix_dev object in order to free its storage. The problem is, this object is not stored as drvdata with the device; since the kfree function will accept a NULL pointer, the memory for the vfio_matrix_dev object is never freed. Since the device being released is contained within the vfio_matrix_dev object, the container_of macro will be used to retrieve its pointer.

Currently i915_gem_object_is_framebuffer() doesn't treat the BO containing the framebuffer's DPT as a framebuffer itself. This means eg. that the shrinker can evict the DPT BO while leaving the actual FB BO bound, when the DPT is allocated from regular shmem. That causes an immediate oops during hibernate as we try to rewrite the PTEs inside the already evicted DPT obj. TODO: presumably this might also be the reason for the DPT related display faults under heavy memory pressure, but I'm still not sure how that would happen as the object should be pinned by intel_dpt_pin() while in active use by the display engine...
