Ah, I see bpf_core_types_are_compat() after sync'ing my local repo. It
seems the perfect fit for my use case. I only found the
btf_equal_xxx() defined in btf.c when posting these patches. I can
test and use bpf_core_types_are_compat() in v2. Thanks for pointing it
out and explaining the public APIs

There is a race between the assignment of `table->data` and write value
to the pointer of `table->data` in the __do_proc_doulongvec_minmax().
Fix this by duplicating the `table`, and only update the duplicate of
it. And introduce a helper of proc_hugetlb_doulongvec_minmax() to
simplify the code.

DAX uses ->iomap_begin path which gets called to map/allocate
extents. In order to avoid starting journal txn where extent
allocation is not required, we need to check if ext4_map_blocks()
has returned any mapped extent entry.

Currently in case of DAX, we are starting a journal txn everytime for
IOMAP_WRITE case. This can be optimized away in case of an overwrite
(where the blocks were already allocated).
This could give a significant performance boost for multi-threaded writes
specially random writes.

Hi Len,
Thanks for the quick turn around. My apologies for not checking the tree before
sending a follow-up email.
If you decide you prefer to change intel_idle - I'd be happy to do the work if
you'd like. Just let me know.
Thanks,

Now with zstd compressed kernel & initrd upstream, we would rather
compress everything with one type of compressor, so I added support
for zstd compressed firmware loading, too.
Tested on x86-64, sparc64 and mips64.

If you need this only for timeout calculation just divide it in
