2025-05-12btrfs: add back warning for mount option commit values exceeding 300Kyoji Ogasawara
The Btrfs documentation states that if the commit value is greater than 300 a warning should be issued. The warning was accidentally lost in the new mount API update.

2025-05-12btrfs: fix folio leak in submit_one_async_extent()Boris Burkov
If btrfs_reserve_extent() fails while submitting an async_extent for a compressed write, then we fail to call free_async_extent_pages() on the async_extent and leak its folios. A likely cause for such a failure would be btrfs_reserve_extent() failing to find a large enough contiguous free extent for the compressed extent. I was able to reproduce this by: 1. mount with compress-force=zstd:3 2. fallocating most of a filesystem to a big file 3. fragmenting the remaining free space 4. trying to copy in a file which zstd would generate large compressed extents for (vmlinux worked well for this) Step 4. hits the memory leak and can be repeated ad nauseam to eventually exhaust the system memory. Fix this by detecting the case where we fallback to uncompressed submission for a compressed async_extent and ensuring that we call free_async_extent_pages().

2025-05-12btrfs: fix discard worker infinite loop after disabling discardFilipe Manana
If the discard worker is running and there's currently only one block group, that block group is a data block group, it's in the unused block groups discard list and is being used (it got an extent allocated from it after becoming unused), the worker can end up in an infinite loop if a transaction abort happens or the async discard is disabled (during remount or unmount for example). This happens like this: 1) Task A, the discard worker, is at peek_discard_list() and find_next_block_group() returns block group X; 2) Block group X is in the unused block groups discard list (its discard index is BTRFS_DISCARD_INDEX_UNUSED) since at some point in the past it become an unused block group and was added to that list, but then later it got an extent allocated from it, so its ->used counter is not zero anymore; 3) The current transaction is aborted by task B and we end up at __btrfs_handle_fs_error() in the transaction abort path, where we call btrfs_discard_stop(), which clears BTRFS_FS_DISCARD_RUNNING from fs_info, and then at __btrfs_handle_fs_error() we set the fs to RO mode (setting SB_RDONLY in the super block's s_flags field); 4) Task A calls __add_to_discard_list() with the goal of moving the block group from the unused block groups discard list into another discard list, but at __add_to_discard_list() we end up doing nothing because btrfs_run_discard_work() returns false, since the super block has SB_RDONLY set in its flags and BTRFS_FS_DISCARD_RUNNING is not set anymore in fs_info->flags. So block group X remains in the unused block groups discard list; 5) Task A then does a goto into the 'again' label, calls find_next_block_group() again we gets block group X again. Then it repeats the previous steps over and over since there are not other block groups in the discard lists and block group X is never moved out of the unused block groups discard list since btrfs_run_discard_work() keeps returning false and therefore __add_to_discard_list() doesn't move block group X out of that discard list. When this happens we can get a soft lockup report like this: [71.957] watchdog: BUG: soft lockup - CPU#0 stuck for 27s! [kworker/u4:3:97] [71.957] Modules linked in: xfs af_packet rfkill (...)

2025-05-12drm: nova-drm: add initial driver skeletonDanilo Krummrich
Add the initial nova-drm driver skeleton. nova-drm is connected to nova-core through the auxiliary bus and implements the DRM parts of the nova driver stack. For now, it implements the fundamental DRM abstractions, i.e. creates a DRM device and registers it, exposing a three sample IOCTLs. DRM_IOCTL_NOVA_GETPARAM - provides the PCI bar size from the bar that maps the GPUs VRAM from nova-core DRM_IOCTL_NOVA_GEM_CREATE - creates a new dummy DRM GEM object and returns a handle DRM_IOCTL_NOVA_GEM_INFO - provides metadata for the DRM GEM object behind a given handle I implemented a small userspace test suite [1] that utilizes this interface.

2025-05-12drm/msm/dp: Introduce link training per-segment for LTTPRsAleksandrs Vinarskis
DisplayPort requires per-segment link training when LTTPR are switched to non-transparent mode, starting with LTTPR closest to the source. Only when each segment is trained individually, source can link train to sink. Implement per-segment link traning when LTTPR(s) are detected, to support external docking stations. On higher level, changes are: * Pass phy being trained down to all required helpers * Run CR, EQ link training per phy * Set voltage swing, pre-emphasis levels per phy Since at least some LTTPRs (eg. Parade PS8830) do not correctly report voltage-swing, pre-emphasis level 3 support, always assume level 3 is supported. This is permitted under DP 2.1(a) section 3.6.7.2 stating that LTTPR shall set its transmitter levels as close as possible to those requested by the DPTX, if the DPTX sets the voltage swing or pre-emphasis to a level that the LTTPR does not support. It shall be noted that LTTPR’s level choosing is implementation-specific. This ensures successful link training both when connected directly to the monitor (single LTTPR onboard most X1E laptops) and via the docking station (at least two LTTPRs).

If io_region_init_ptr() finds that the pages are coalescable, also check if the first page is a HighMem page or not. If it is, fall through to the usual vmap() mapping rather than attempt to get the unmapped page address.
