Split openat/close test into two separate tests
...
If an older kernel fails the `openat` test because of `AT_FDCWD`
then we don't want to skip the `close` test.

std: Add pow(a,b) for big ints
...
Implemented following Knuth's "Evaluation of Powers" chapter in TAOCP,
some extra complexity is needed to make sure there's no aliasing and
avoid allocating too many limbs.
A brief example to illustrate why the last point is important:
consider 10^123, since 10 is well within the limits of a single limb we
can safely say that the result will surely fit in:
⌈log2(10)⌉ bit * 123 = 492 bits = 7 limbs
A naive calculation using only the number of limbs yields:
1 limb * 123 = 123 limbs
The space savings are noticeable.

Alternative strategy to avoid calling stat()

This is an optimization as it avoids an extra syscall, but it's also a

Use load acquire semantics when reading the SQPOLL wakeup flag
...
Ensures that the wakeup flag is read after the tail pointer has been
written. It's important to use memory load acquire semantics for the
flags read, otherwise the application and the kernel might not agree on
the consistency of the wakeup flag, leading to I/O starvation.

Implement ghash aggregated reduction
...
Performance increases from ~400 MiB/s to 450 MiB/s at the expense of
extra code. Thus, aggregation is disabled on ReleaseSmall.
Since the multiplication cost is significant compared to the reduction,
aggregating more than 2 blocks is probably not worth it.
