Reiser4 Ported Early To The Linux 5.12 Kernel

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.

READFILE System Call Rebased For More Efficient Reading Of Small Files

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.

Btrfs Will Finally "Strongly Discourage" You When Creating RAID5 / RAID6 Arrays

For a number of years it has been known that the Btrfs RAID5 and RAID6 code is potentially unsafe and not nearly as mature as the native RAID support found in this Linux file-system for other levels. Finally now we are seeing the Btrfs user-space programs warn the user when attempting to create such Btrfs native RAID 5/6 configurations.

New NTFS Driver Misses Out On Linux 5.12 But Revved A 22nd Time

While Linux 5.12 has many great new features, what you won't find in the mainline kernel is the new "NTFS3" kernel driver developed by Paragon Software for NTFS file-systems. That driver is still coming for a future kernel and has now been sent out a twenty-second time for review.

IO_uring Will Be Even Faster With Linux 5.12

IO_uring has been one of the greatest Linux kernel innovations in recent times. IO_uring for more efficient asynchronous I/O has continued getting faster and introducing new features over the past two years and for the upcoming Linux 5.12 cycle will be even faster.

F2FS With Linux 5.12 To Allow Configuring Compression Level

While the Flash-Friendly File-System (F2FS) allows selecting between your choice of optional compression algorithms like LZO, LZ4, and Zstd -- plus even specifying specific file extensions to optionally limit the transparent file-system compression to -- it doesn't allow easily specifying a compression level. That is fortunately set to change with the Linux 5.12 kernel this spring.

Paragon Publishes Latest NTFS File-System Patches For Linux

One of the pleasant kernel surprises in 2020 was Paragon Software looking to upstream their previously commercial NTFS driver. This driver offers read-write support and more advanced capabilities than the current read-focused NTFS driver presently in the mainline kernel and better off than the other FUSE-based driver. This driver hasn't been mainlined yet but Paragon published new patches on Christmas.

Linux 5.11 XFS Will Flag File-Systems In Need Of Repair

The main feature change for the XFS driver code in Linux 5.11 is adding a new "needs repair" feature flag. When the XFS code marks a file-system as needing repair, it will refuse to mount until the xfs_repair operation is run on it.
