Linux 6.15-rc4 is now available after a rather eventful week and about one month to go until the stable Linux 6.15.
This week was rather busy with spotting a significant performance regression in Linux 6.15 Git during ongoing tests at Phoronix. Fortunately, the regression was quickly resolved and is all fixed up for Linux 6.15-rc4.
That was quite a regression that was initially introduced the week before but thankfully is fixed with Linux 6.15-rc4. There is though a separate performance regression I am looking into at the moment.
Linux 6.15-rc4 also fixes x86 32-bit kernels from crashing if more than 4GB of memory is installed in the system.
The Bcachefs file-system has fixed up its case insensitive/folding support while Linus Torvalds reminded the kernel development community his extreme distaste for case-insensitive file-systems.
Onward to additional Linux 6.15 testing and digging further into this newest performance regression I should have bisected and spelled out in another day or two.
While Linux 6.15-rc4 was tagged more than a half hour ago, Linus Torvalds has yet to comment on today’s release via the Linux kernel mailing list.
