nullfs: close a race when syncing inotify flags from the lower vnode
After a bypassed VOP, nullfs mirrors the lower vnode's inotify state
onto the upper vnode. The flags were checked with lockless reads
before being updated with the asserting flag set/unset primitives, so
two threads syncing the same vnode concurrently (or a sync racing a
watch being established) could both decide to make the same change;
the loser then trips the "flags already set" assertion on an
INVARIANTS kernel. On other kernels the race is harmless.
Keep the lockless check as the fast path, but re-make the decision
under the vnode interlock before actually changing the flags.
Reproduced in a 4-CPU VM with one thread cycling an inotify watch on
a lower-filesystem file while several threads stat(2) the same file
through a nullfs mount: the unpatched INVARIANTS kernel panics under
this load, the patched kernel runs it to completion.

Stop a VM before destroying its backing zvols on delete
Deleting a VM with `zvols=true` tore down the backing zvols before stopping the domain, so ZFS could be pulled out from under a live qemu process — risking in-flight corruption and leaving zvols that fail to destroy with EBUSY. The `force` option also didn't really gate deleting a running VM despite what its description implied.
Reject deleting an active (running/suspended) VM unless `force` is set, and stop/undefine the domain before touching its zvols so the block devices are released first; the `force` field description now matches that behaviour. Picked up a few smaller VM-plugin tidy-ups along the way: clone rollback unwinds the snapshots/clones (and half-created VM record) it made if something fails partway, the disk-convert guard treats suspended VMs like running ones, and the convert path check looks at the real destination directory rather than its parent — with unit tests for the convert checks.
[ADT] Add begin and end to EytzingerTableSpan and EytzingerTable (NFC) (#210478)
This patch adds iterator and const_iterator type aliases as well as
begin() and end() methods to EytzingerTableSpan and EytzingerTable.
I'm going to be using these as part of the SecNameTable in the
Eytzinger layout.

[Github] symlink `llvm-tools` in libc container (#210561)
Missed thing in #210414. We need to symlink the LLVM tools that are
under `/usr/lib/llvm-23/bin/` to avoid errors like this because the LLVM
tools have a `-23` suffix when they're installed inside the container

graphics/ruby-mini-magick: update to 5.3.2
5.3.2 (2026-07-14)
* Restored instantiating legacy MiniMagick::Tool::* classes for backwards
compatibility, which got broken in 5.0.
* Reintroduced manual timeouts instead of relying on $MAGICK_TIME_LIMIT,
which wasn't reliably enforcing the timeout (and isn't compatible with
GraphicsMagick).
[X86][APX] Reuse EFLAGS across multi-predecessor blocks via NF in optimizeCompareInstr (#208184)
Extend optimizeCompareInstr to reuse EFLAGS produced in predecessor
blocks (including via NF variants) when a compare is redundant, covering
multi-predecessor, dominating, and cyclic CFGs. Share the NF-clobber
removal helper with FlagsCopyLowering, correctly handle swapped and
immediate-adjusted flag reuse, and simplify EFLAGS live-in marking.
Adds MIR tests exercising multi-predecessor reuse over cyclic and
dominating CFGs, including a multi-level idom walk.

use strncmp instead of memcmp in complt()
cpos is not necessarely shorter than lh->l_name length, so we might end
up memcmp'ing out of bounds.

[mlir][bufferization] Fix stale BufferOriginAnalysis in BufferDeallocationSimplification (#210105)
Fixes #205228
This change fixes a use-after-free bug in the
BufferDeallocationSimplification pipeline caused by the greedy pattern
rewriter deleting operation tracked by the BufferOriginAnalysis.
BufferViewFlowAnalysis (internally used by BufferOriginAnalysis) creates
the dependencies map once during initialization. In this specific case,
the folder removed the `memref.cast` ops making later uses a
use-after-free bug.
Below is the snippet of running the pass using
`-debug-only=greedy-rewriter`. It erases a `memref.cast` and crashes in
RemoveDeallocMemrefsContainedInRetained.
