If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will
allocate 'just enough' pages to run the test. In the SEAL-FUTURE-WRITE
test the mfd_fail_write routine maps the file, but does not unmap. As a
result, two hugetlb pages remain reserved for the mapping. When the
fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb
pages, it is short by the two reserved pages.
Fix by making sure to unmap in mfd_fail_write.

mm: fix use-after-free bug when mm->mmap is reused after being freed
oom reaping (__oom_reap_task_mm) relies on a 2 way synchronization with
exit_mmap. First it relies on the mmap_lock to exclude from unlock
path[1], page tables tear down (free_pgtables) and vma destruction.
This alone is not sufficient because mm->mmap is never reset.
For historical reasons[2] the lock is taken there is also MMF_OOM_SKIP
set for oom victims before.
The oom reaper only ever looks at oom victims so the whole scheme works
properly but process_mrelease can opearate on any task (with fatal
signals pending) which doesn't really imply oom victims. That means
that the MMF_OOM_SKIP part of the synchronization doesn't work and it
can see a task after the whole address space has been demolished and
traverse an already released mm->mmap list. This leads to use after
free as properly caught up by KASAN report.
Fix the issue by reseting mm->mmap so that MMF_OOM_SKIP synchronization
is not needed anymore. The MMF_OOM_SKIP is not removed from exit_mmap
yet but it acts mostly as an optimization now.

a page table lookup check for huge PTE bit in the page table to
differentiate between a huge pte entry and a pointer to pte page. A
huge_pte_alloc won't mark the page table entry huge and hence kernel
should not use huge_pte_offset after a huge_pte_alloc.

Currently, --entries uses -e as the short version in the hist mode of
timerlat and osnoise tools. But as -e is already used to enable events
on trace sessions by other tools, thus let's keep it available for the
same usage for all rtla tools.
Make -E the short version of --entries for hist mode on all tools.
Note: rtla was merged in this merge window, so rtla was not released yet.

Al Viro brought it to my attention that the dentries may not be filled

possibly crash. It should only be called if parse_options() succeeds
totally anyway.
He suggested the logical place to do the update is in apply_options().

RDMA/cma: Do not change route.addr.src_addr outside state checks
If the state is not idle then resolve_prepare_src() should immediately
fail and no change to global state should happen. However, it
unconditionally overwrites the src_addr trying to build a temporary any
address.
For instance if the state is already RDMA_CM_LISTEN then this will corrupt
the src_addr and would cause the test in cma_cancel_operation():
if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev)
Which would manifest as this trace from syzkaller:
BUG: KASAN: use-after-free in __list_add_valid+0x93/0xa0 lib/list_debug.c:26
Read of size 8 at addr ffff8881546491e0 by task syz-executor.1/32204
This is indicating that an rdma_id_private was destroyed without doing
cma_cancel_listens().
Instead of trying to re-use the src_addr memory to indirectly create an
any address derived from the dst build one explicitly on the stack and
bind to that as any other normal flow would do. rdma_bind_addr() will copy
it over the src_addr once it knows the state is valid.
This is similar to commit bc0bdc5afaa7 ("RDMA/cma: Do not change
route.addr.src_addr.ss_family")
