1. Prominent features

1.1. ID mapping in mounts

This release introduces the concept of idmapped mounts. This allows to map the user id of a mount to a different one. This makes possible to share files more easily between multiple users or multiple machines especially in complex scenarios. For example, idmapped mounts will be used in the implementation of portable home directories in systemd-homed.service(8) where they allow users to move their home directory to an external storage device and use it on multiple computers where they are assigned different uids and gids. It also makes possible to share files from the host with unprivileged containers without having to change ownership permanently, and many other This initial implementation comes with ports for fat and ext4, with other file systems being prepared in next releases

1.2. Allow selecting preempting model at boot and run time

Currently, using one preempt model (none/voluntary/model) is a build time configuration option. This release adds the preempt=none/voluntary/full boot options (default: full), to allow distros to build a PREEMPT kernel but fall back to close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via a boot time selection. There's also the /debug/sched_debug switch to do this runtime. This feature is implemented via runtime patching (a new variant of static calls).

4. File systems

BTRFS
- Support subpage block size (currently read-only support) commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- Zoned mode, first working version but with limitations commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- Do not block on deleted block group mutex in the cleaner, avoids some long stalls. Also less lock contention related to running delayed refs, let just one thread do the flushing when there are many inside transaction commit commit, commit, commit, commit, commit, commit, commit, commit
- Improve Preemptive background flushing: separate the logic from ticket reservations, improve the accounting and decisions when to flush in low space conditions commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- dbench workload improvements: avoid unnecessary work when logging inodes, fewer fallbacks to transaction commit and thus less waiting for it (+7% throughput, -20% latency) commit, commit, commit, commit, commit, commit, commit
XFS
- Speed up file fsyncs by reducing iolock cycling commit, commit
- Increase the default parallelism levels of pwork clients. On fast systems this will speed up quotacheck by a large factor commit
- Allow sysadmins to tweak the CPU affinities and maximum concurrency levels of quotacheck and background blockgc worker pools commit
- Expose inobtcount in xfs geometry commit
F2FS
- Support compress level commit
- Introduce checkpoint_merge mount option commit
- Introduce a new per-sb directory in sysfs commit
- Add ckpt_thread_ioprio sysfs node commit
- Introduce sb_status sysfs node commit
NFS
- Add mount options supporting eager writes writes=lazy/eager/wait. The mount option basically controls how the write() system call works. writes=lazy is the default, and keeps the current behaviour. writes=eager means we send off the write immediately as an unstable write to the server. writes=wait means we send off the write as an unstable write, and then wait for the reply commit, commit, commit
- Support the -owrite option in /proc/self/mounts and mountinfo commit
- Report per-export stats commit
- Remove unused stats counters commit
CIFS
- Add new mount parameter acdirmax to allow caching metadata for directories more loosely than file data commit, commit
- Add new mount parameter "acregmax" for distinct file and directory metadata timeout commit
GFS2

13.2. Power Management

In modern systems the platform performance, temperature, fan and other hardware related characteristics are often dynamically configurable with one of several 'platform-profiles', with either a bias towards low-power consumption or towards performance (and higher power consumption and thermals). This feature introduces a new platform_profile sysfs API which offers a generic API for selecting the performance-profile of these automatic-mechanisms commit, commit
