Subject: [GIT PULL] non-MM udpates for 6.17-rc1
Linus, please merge mm.git's non-MM updates for the next -rc1 cycle,
I'm seeing two conflicts against your current tree. Those, along with
their linux-next resolutions are:
kernel/panic.c, vs sysctl tree:
https://lkml.kernel.org/r/20250708190003.4eabc8ab@canb.auug.org.au
lib/Kconfig.debug, vs paulmck tree:
https://lkml.kernel.org/r/20250729104245.6be6957a@canb.auug.org.au
Thanks.

tools/getdelays: add backward compatibility for taskstats version (2025-08-02 12:01:41 -0700)
----------------------------------------------------------------
Significant patch series in this pull request:
- The 2 patch series "squashfs: Remove page->mapping references" from
Matthew Wilcox gets us closer to being able to remove page->mapping.
- The 5 patch series "relayfs: misc changes" from Jason Xing does some
maintenance and minor feature addition work in relayfs.
- The 5 patch series "kdump: crashkernel reservation from CMA" from Jiri
Bohac switches us from static preallocation of the kdump crashkernel's
working memory over to dynamic allocation. So the difficulty of
a-priori estimation of the second kernel's needs is removed and the
first kernel obtains extra memory.
- The 5 patch series "generalize panic_print's dump function to be used
by other kernel parts" from Feng Tang implements some consolidation and
rationalizatio of the various ways in which a faiing kernel splats
information at the operator.
