    Phoronix: Linux 5.17-rc1 Released A Little Bit Early But With Shiny New Features

    Due to family travels Linus Torvalds has released Linux 5.17-rc1 a little bit early that marks the end of the Linux 5.17 merge window...

    Nice!
    Being in Europe, this is not early at all, it's quite on time!
    I hoped until the last moment that the Zst code will be updated to the latest version (1.5.1) from the non-existing upstream (1.4.10) version, but I guess somebody wanted to wait probably for more bugs to be reported and fixed, which probably happened with the 1.5.2 version released 3 days ago.
    Anyway, I hope this will happen in 5.18 to add even more awesomeness to the BTRFS improvements in this version.
    Now, I'm eager to see some benchmarks, especially in the storage and networking areas, maybe even gaming.

              5.17-rc1 is running great. Ran some quick benchmarks and getting new highs also in the pts/osbench benchmarks compared to 5.16. We always welcome more performance.

                This also marks me having 10 patches in the kernel. All pretty minor stuff, but hey, it's something :P

                  Awesome, we thank you for your service. And I'll leave you with this:

                    The kernel Makefile has slightly changed in 5.17 which is breaking building kernel modules with DKMS.
                    Code:
                    DKMS make.log for ryzen_smu-0.1.2 for kernel 5.17.0-0.rc1.znver3.fc35.x86_64 (x86_64)
                    Sun Jan 23 12:37:43 PM EST 2022
                    make[1]: Entering directory '/usr/src/kernels/5.17.0-0.rc1.znver3.fc35.x86_64'

                    /bin/sh: -c: line 1: `if [ "gcc (GCC) 11.2.1 20211203 (Red Hat 11.2.1-7)" != ""gcc (GCC) 11.2.1 2021
                    1203 (Red Hat 11.2.1-7)"" ]; then \'

                    make: *** [Makefile:28: modules] Error 2
                    In 5.16 the prepare command was
                    Code:
                    prepare: CC_VERSION_TEXT := $(CC_VERSION_TEXT)
                    prepare:
                        @if [ "$(CC_VERSION_TEXT)" != $(CONFIG_CC_VERSION_TEXT) ]; then \
                            echo >&2 "warning: the compiler differs from the one used to build the kernel"; \
                            echo >&2 " The kernel was built by: "$(CONFIG_CC_VERSION_TEXT); \
                            echo >&2 " You are using: $(CC_VERSION_TEXT)"; \
                        fi
                    In 5.17 the prepare command is now
                    Code:
                    prepare: CC_VERSION_TEXT := $(CC_VERSION_TEXT)
                    prepare:
                        @if [ "$(CC_VERSION_TEXT)" != "$(CONFIG_CC_VERSION_TEXT)" ]; then \
                            echo >&2 "warning: the compiler differs from the one used to build the kernel"; \
                            echo >&2 " The kernel was built by: $(CONFIG_CC_VERSION_TEXT)"; \
                            echo >&2 " You are using: $(CC_VERSION_TEXT)"; \
                        fi
                    Because CONFIG_CC_VERSION_TEXT isn't being expanded like CC_VERSION_TEXT it is being double quoted and the test fails.
                    This patch will fix it.
                    Code:
                    diff --git a/Makefile b/Makefile
                    index 299e0c9..12535f6 100644
