Depends: !2212

Set of changes to level the RHEL-10 MM-core and dependencies codebase up to upstream's v6.16.

Signed-off-by: Rafael Aquini [email protected]

@jmoyer1 Thanks for the heads up and pointing these out! The reason I don't have these commits is that kerneloscope doesn't include/recognize any of them in any series also touching MM-related files.

It is my understanding that 5b27dfb1d7b59 ("s390/dcssblk: Add DAX support") is a v6.18 commit, which means the functionality removal will be transitory and only remain present across our interim builds as I plow through with the next series of incremental updates, or in the worst-case scenario, if devel time runs short, disabled in the short-lived 10.3 stream and reenabled for the 10.4 EUS stream.

I'll get to work on (2) for the moment.

Thank you, again!

Restartable sequence is a kernel feature that enables userspace code (like glibc) to handle percpu variables and even implement userspace spinlocks. It complements futex that enables userspace mutex. Add that as part of the locking component.

I've been thinking about that as well, but I believe we should probably open a separate MR to go over the "exclusionary" review and update. The reason for that is that there are more overlaps like that across the space, i.e., the X86 subsystem regex is also very broad and ends up picking several other files that belong to MM and core-kernel.

MR: !2197

This MR backports most of the kernel/time commits up to v6.18 with fixes beyond that. The major exception is some namespace related commits which have to be done separately.

Update the include list to reflect the current state of the maintained codebase and reduce the occurrence of "Unowned Files" label in gitlab. Also adjust the jiraComponent and SST fields for the LIB subcomponent.

@zhijwang thank you! I updated the jira as requested. lemme know if anything else is needed!

@zhijwang, we need to waive the "Module diff test" results for this MR, as it brings in upstream changes that remove ZBUD, which is why the tests here are failing. Also, please merge the following kernel-tests MR redhat/centos-stream/tests/kernel/kernel-tests!4601, which aims to address this removal for RHEL-10 and forward
