This does not provide support for extendable user-space block devices without having to stop and restart the underlying ublkb block device causing IO interruption.

This works just like pipe2(2), except it also supports fixed file descriptors. Used in a similar fashion as for other fd instantiating opcodes (like accept, socket, open, etc), where sqe->file_slot is set appropriately if two direct descriptors are desired rather than a set of normal file descriptors. sqe->addr must be set to a pointer to an array of 2 integers, which is where the fixed/normal file descriptors are copied to. sqe->pipe_flags contains flags, same as what is allowed for pipe2(2). Future expansion of per-op private flags can go in sqe->ioprio, like we do for other opcodes that take both a "syscall" flag set and an io_uring opcode specific flag set.

2025-04-17net: add UAPI to the header guard in various network headersJakub Kicinski19-46/+46
fib_rule, ip6_tunnel, and a whole lot of if_* headers lack the customary _UAPI in the header guard. Without it YNL build can't protect from in tree and system headers both getting included. YNL doesn't need most of these but it's annoying to have to fix them one by one. Note that header installation strips this _UAPI prefix so this should result in no change to the end user.

2025-04-15fuse: add more control over cache invalidation behaviourLuis Henriques1-1/+5
Currently userspace is able to notify the kernel to invalidate the cache for an inode. This means that, if all the inodes in a filesystem need to be invalidated, then userspace needs to iterate through all of them and do this kernel notification separately. This patch adds the concept of 'epoch': each fuse connection will have the current epoch initialized and every new dentry will have it's d_time set to the current epoch value. A new operation will then allow userspace to increment the epoch value. Every time a dentry is d_revalidate()'ed, it's epoch is compared with the current connection epoch and invalidated if it's value is different.

This will allow the application (AFS or userspace) to interact with the process if it wants to and put values into user-defined fields.

Fix the frequency returned to the user space by the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL. The kernel driver returned CPU frequency for MTL and bare PLL frequency for LNL - this was inconsistent and incorrect for both platforms. With this fix the driver returns maximum frequency of the NPU data processing unit (DPU) for all HW generations. This is what user space always expected. Also do not set CPU frequency in boot params - the firmware does not use frequency passed from the driver, it was only used by the early pre-production firmware. With that we can remove CPU frequency calculation code. Show NPU frequency in FREQ_CHANGE interrupt when frequency tracking is enabled.
