    Phoronix: EXT4 Gets A Nice Batch Of Fixes For Linux 5.8

    Ted Ts'o sent in the EXT4 file-system changes on Thursday for Linux 5.8 as the summer 2020 kernel release...

    There is also clean-ups to EXT4's fiemap handling, multiple block allocator, and other improvements.
    is --> are (English is full of traps for unwary foreigners, so this is not criticism, just information. Irregular verbs are a pain in all languages)

    I guess the fee-, foe-, and fum-map handling didn't need clean-up. ;-)

        Let's make EXT5 with all the features of ZFS and BTRFS. After all, it's the most successful Linux filesystem.

          It's gonna take a LONG time if they began to think like those filesystems u mentioned and after they decide, its gonna take another LONG time ready to be released in EXT6.

          Although I would love to see that happens faster.

            Since when is Michael a foreigner? Last time I checked he was American, born and raised.

              No thanks.
              The only feature missing from ext4 is data Checksumming. Which is useless anyway because all disks do a crc themselves anyway.

                If it is so useless then how did it catch a failing disk in my btrfs array back in 2014 or so?

                I had a Western Digital 2 TB drive that must have had some controller or cache RAM failure, because it returned zeroes for a set of blocks. You could write to those blocks, and it would return the new data for a while, then it was right back to zeroes. No block errors reported either.

                So much for disk CRC.

                  Oh look EXT4 has bugs. It must not be a stable filesystem! Quick everyone switch to ZFS!

                  Yeah, I like to say that because it's exactly what the btrfs critics say every time there's a bugfix release. It's just as ridiculous.
