Subject: [GIT PULL] non-MM updates for 6.16-rc1
Linus, please merge this set of other-than-MM patches for the 6.16-rcX
cycle, thanks.
Conflicts which I'm seeing today, and their linux-resolutions:

llist: make llist_add_batch() a static inline (2025-05-27 19:40:34 -0700)
----------------------------------------------------------------
- The 3 patch series "hung_task: extend blocking task stacktrace dump to
semaphore" from Lance Yang enhances the hung task detector. The
detector presently dumps the blocking tasks's stack when it is blocked
on a mutex. Lance's series extends this to semaphores.
- The 2 patch series "nilfs2: improve sanity checks in dirty state
propagation" from Wentao Liang addresses a couple of minor flaws in
nilfs2.
- The 2 patch series "scripts/gdb: Fixes related to lx_per_cpu()" from
Illia Ostapyshyn fixes a couple of issues in the gdb scripts.
- The 9 patch series "Support kdump with LUKS encryption by reusing LUKS
volume keys" from Coiby Xu addresses a usability problem with kdump.
When the dump device is LUKS-encrypted, the kdump kernel may not have
the keys to the encrypted filesystem. A full writeup of this is in the
series [0/N] cover letter.
- The 2 patch series "sysfs: add counters for lockups and stalls" from
Max Kellermann adds /sys/kernel/hardlockup_count and
/sys/kernel/hardlockup_count and /sys/kernel/rcu_stall_count.
- The 3 patch series "fork: Page operation cleanups in the fork code"
from Pasha Tatashin implements a number of code cleanups in fork.c.
- The 3 patch series "scripts/gdb/symbols: determine KASLR offset on
s390 during early boot" from Ilya Leoshkevich fixes some s390 issues in
the gdb scripts.
