Linux 5.15-rc2 as the latest weekly release candidate for the next version of the Linux kernel is now available. Linux 5.15 is expected to be released as a stable version around the beginning of November. Just a week after the merger window ended, Linux 5.15-rc2 has seen many fixes in the past week.
The projects after the merge window that attracted our attention this week include improved GCC version requirements for the supported baseline compiler version, Linux 5.15 is now less destructive to DEC Alpha Jensen systems, and SMB3 files in the KSMBD kernel Important repair of the server.
Linus Torvalds pointed out in the 5.15-rc2 announcement that he spent a lot of time this week studying the problems caused by the -Werror default value restored by the Linux kernel during the merge window. Various fixes – including DEC Jensen’s fixes – have come from research on the problems caused by extending compiler warnings to errors.
Linus added in the 5.15-rc2 announcement:
Is it done? But in general, I feel pretty good about all of this, even if it means I have been looking at some very strange and bad code. Who knows that after so many years, I am still worried about some strange EISA drivers? Change the rhythm a little bit;) The performance regression of Linux 5.15 is indeed retained in 5.15-rc2, while waiting for further test patches, hoping to solve it before the 5.15 stable version. I am in contact with the relevant developers.
