Back in April the out-of-tree Reiser4 file-system was updated for Linux 5.12 compatibility while now with Linux 5.13 being right around the corner, Edward Shishkin has updated the experimental Reiser5 file-system code for v5.12 compatibility.

The Linux kernel currently has code to allow booting an initial root file-system via NFS or CIFS for non-blockdevice file-systems while a new patch aims to allow for mounting of arbitrary non-block device file-systems as root.

Last month plans were published for Fedora Cloud 35 to use the Btrfs file-system by default, similar to Fedora Workstation using Btrfs by default for several releases. That plan has now been signed off on by FESCo allowing for this change to happen.

A big patch series out of Red Hat is now queued into the XFS file-system development Git branch that is part of the new material for the upcoming Linux 5.14 cycle.

The Flash-Friendly File-System (F2FS) saw queued into its "dev" tree this week the new compress_cache mount option ahead of the upcoming Linux 5.14 cycle.

The seventh release candidate of OpenZFS 2.1 is now available for testing while it looks like soon it will cross the finish line as the latest feature release for this open-source ZFS file-system implementation for Linux and FreeBSD systems.

Queued up now into the EXT4 file-system's "dev" tree is the recent work on a journal checkpoint ioctl (EXT4_IOC_CHECKPOINT) and optional support for TRIM/discard or zero-out support on journal flushes. This is the work that came about in recent months in working to ensure the privacy of deleted file names from the system.

Linux's RAW driver (RAW_DRIVER) for providing direct I/O access to block devices is finally set to be removed with the Linux 5.14 kernel this summer since its deprecation all the way back in the mid 2000s and its use has been discouraged even longer.

Yet another release candidate of OpenZFS 2.1 is now available for testing and this time around there are some interesting changes to note.

With the Linux 5.14 cycle this summer the Flash-Friendly File-System (F2FS) should land its new "RO" feature read-only mode.

Red Hat engineers have scored an impressive performance optimization to the DeviceMapper (DM) code that is now queued up for merging with the Linux 5.14 cycle.

Two weeks have passed since OpenZFS 2.1-rc4 while today a fifth release candidate was issued for this open-source ZFS file-system implementation for Linux and FreeBSD systems.

The Linux 5.13 kernel has initial support for dealing with SPI one-time programmable (OTP) flash memory regions.

Adding to the growing list of changes for Linux 5.13 is the UBIFS file-system now using Zstd for file-system compression by default.

The kernel's Device Mapper (DM) code with Linux 5.13 has some improvements worth mentioning this cycle.

The Flash-Friendly File-System (F2FS) updates for Linux 5.13 have been submitted in providing the latest features for this flash-optimized file-system.

Merged as part of the block subsystem changes for the Linux 5.13 were the usual assortment of enhancements to the exciting IO_uring. With this next kernel there is yet even better performance out of this morning Linux I/O interface.

The OrangeFS open-source parallel file-system designed for cluster computing has a huge performance improvement to its read speeds with Linux 5.13.

Users of the Btrfs file-system can enjoy a number of improvements with the in-development Linux 5.13 kernel.

It's looking like the OpenZFS 2.1 open-source ZFS file-system implementation for Linux and FreeBSD systems will soon be ready for release.

The Samsung-led CIFSD as an in-kernel SMB3 file-sharing server continues on its trajectory toward the mainline Linux kernel.

OpenZFS 2.1 is nearing release as the next feature update to this open-source ZFS file-system implementation currently supporting Linux and FreeBSD systems.

While EXT4 supports both case-folding for optional case insensitive filenames and does support file-system encryption, at the moment those features are mutually exclusive. But it looks like the upcoming Linux 5.13 kernel will allow casefolding and encryption to be active at the same time.

Normally we don't see the out-of-tree Reiser4 file-system ported to new Linux kernel releases until after the inaugural stable release, but this time around Reiser4 has seen an early port to the near-final Linux 5.12 kernel.

At the end of March the release candidate phase began for the upcoming OpenZFS 2.1 open-source ZFS file-system on Linux and FreeBSD systems. The second release candidate is now available for this noteworthy OpenZFS update.

The past year there has been work led by Greg Kroah-Hartman on a "READFILE" system call for efficiently reading small files such as for data exposed via sysfs. While not yet mainlined, this week the patches for this new system call were re-based giving us hope that perhaps we'll see it with Linux 5.13.

The first release candidate of the forthcoming OpenZFS 2.1 file-system for Linux and FreeBSD systems is now available for testing.

For those running Linux MD RAID10 arrays you may have found the performance around discard requests such as when running MKFS and FSTRIM operations to be rather slow... Well, with Linux 5.13 it will be lightning fast.

It's 2021 and proposed patches by upstream developers would finally remove Linux's legacy IDE driver code.

OpenZFS 2.0.4 is out as the latest version of this open-source ZFS file-system implementation for Linux and FreeBSD systems.
