devel/gitlab-runner: improved start and stop command
The rc system does not wait till the child terminated.
Added a logic to wait for parent and child pid to terminate before
starting it again.
That fixes an issue if gitlab-runner has a long run job active
while a restart is triggered.

[SampleProfile] Support MD5-based ProfileSymbolList (#210235)
This patch speeds up sample profile loading by introducing an
MD5-based ProfileSymbolList (cold symbol list) in extensible binary
profiles.
The sample profile loader spends about a third of its time on loading
and decoding the symbol names in the Profile Symbol List section, yet
we use them only for membership checking purposes via
ProfileSymbolList::contains.
This patch teaches the writer to emit the section as an array of
64-bit GUIDs in the Eytzinger layout. The reader checks the
SecFlagMD5 section flag and sets up an EytzingerTableSpan
pointing into the mmap memory. This achieves both space efficiency
and runtime efficiency.
The new flag, md5-prof-sym-list, is off by default for now.

ld.elf_so: Fix ASSERT macro in xmalloc.c.
1. Use #p, not "p", in the expansion of #define ASSERT(p), for C as of

2. Consistently make ASSERT(...) a single expression.

Fix metadirective loop variant safety checks
Classify candidate and fallback association from raw directive IDs so clauses are only converted for the selected variant.
Recognize data environments selected by enclosing metadirectives from the emitted OpenMP operation ancestry. Add regressions for unselected clauses and nested selected parallel regions.

Pull smb server fixes from Steve French:
"ksmbd server fixes, mostly addressing malformed SMB request
handling and connection/session lifetime issues, including
two information-disclosure or memory-safety bugs in the SMB2
request/response paths.
- validate FILE_ALLOCATION_INFORMATION before block rounding to
prevent a client-controlled overflow from truncating a file.
- pin connections while asynchronous oplock and lease-break
notifications are pending.
- initialize compound SMB2 READ alignment padding, preventing
disclosure of uninitialized heap bytes.
- release the allocated alternate-stream xattr name after rename.

ld.elf_so: Fix more races with recursive threaded dlopen/dlclose.
1. When loading an object, keep track of a finer-grained state for
relocation so that a concurrent _rtld_relocate_objects doesn't
relocate an object too early (e.g., while waiting in
_rtld_load_needed_objects for an object that is concurrently being
dlclosed to finish before we can map it afresh) leading to
spurious symbol resolution failures:
- OBJRELOC_NONE (0): object has been created but the rtld state
isn't enough to attempt relocation yet (either not all DT_NEEDED
entries have been resolved, or the dldags lists have not yet
been populated)
- OBJRELOC_READY (1): object has been created and rtld state is
ready to relocate (all DT_NEEDED entries have been resolved and
the dldags lists have been populated), but object has not yet
been relocated.

[docs] Rewrite 19 LLVM docs from reST to markdown (#208798)
Tracking issue: #201242
[Migration
guide](https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines)
This is a stacked PR based on #208800, which does the file rename to
preserve history.
This was prepared with rst2myst plus LLM-assisted cleanup. I paged
through all the generated HTML looking for migration artifacts, and all
of the differences I could find appear to be formatting error
corrections.
Avoid lowering clauses for inapplicable metadirective variants
Classify raw directive specifications from their leaf directive IDs when
checking for loop association. This keeps clause conversion after applicability
filtering, so unsupported clauses in discarded variants cannot reach lowering.
Add a regression for an inapplicable ASSUME HOLDS variant with a NOTHING fallback.
