    Phoronix: Linux 4.13 Kernel Released

    Linus Torvalds has gone ahead and released the Linux 4.13 kernel...

    Exciting times, especially with the enhancements to Btrfs and XFS, which Tumbleweed uses by default for root and home partitions respectively. I've been trying all the release candidates up through 4.13 rc7 which is quite stable. Had some trouble with wifi and usb on release candidate 1 or 2, but it's been mostly smooth sailing since. Btrfs snapshots have become so simple to use for rolling back system state that I don't think I would want to set up an office computer without them.

      i heart btrfs snapshots too, very very user friendly, they just need to get the rest of the f/s squared away, add a few more compression and an encryption subsystem (preferably one that can accept variable block/key sizes.

          From developer David Sterba's 4.13 git pull message to Linus - http://lkml.iu.edu/hypermail/linux/k...7.0/01853.html -

          "The core updates improve error handling (mostly related to bios), with the usual incremental work on the GFP_NOFS (mis)use removal, refactoring or cleanups. Except the two top patches, all have been in for-next for an extensive amount of time."

          "User visible changes:
          * statx support
          * quota override tunable
          * improved compression thresholds
          * obsoleted mount option alloc_start

          "Core updates:
          * bio-related updates
          - faster bio cloning
          - no allocation failures
          - preallocated flush bios
          * more kvzalloc use, memalloc_nofs protections, GFP_NOFS updates
          * prep work for btree_inode removal
          * dir-item validation
          * qgoup fixes and updates
          * cleanups
          - removed unused struct members, unused code, refactoring
          - argument refactoring (fs_info/root, caller -> callee sink)
          - SEARCH_TREE ioctl docs"

              I will wait a few more release cycles before trying Btrfs. I won't trust Btrfs until is totally deployed on certain critical systems. Maybe Oracle will put more efforts in Btrfs after Solaris goes finally dead, maybe they'll GPL ZFS and merge it in the official repo
