If a file's ACL can be reduced to standard mode bits, update mode
accordingly, persist the change, and update the cached ACL. This keeps
mode and ACL consistent and avoids redundant xattrs.

Add a check for minimum alignment when performing direct I/O reads. If the
file offset or user buffer is not aligned to the device's logical block
size, fall back to buffered I/O instead of continuing with unaligned direct I/O.

Examples (i.e. doctests) may want to show public items such as structs,
thus the `unreachable_pub` warning is not very helpful.
Thus allow it for all doctests.
In addition, remove it from the existing `expect`s we have in a couple
doctests.

Add PCIe RC support on Orion O6 board.
The Orion O6 board includes multiple PCIe root complexes. The current
device tree configuration enables detection and basic operation of PCIe
endpoints on this platform.
GPIO and pinctrl subsystems for this platform are not yet ready for
upstream inclusion. Consequently, attributes such as reset-gpios and
pinctrl configurations are temporarily omitted from the PCIe node
definitions.
Endpoint detection and functionality are confirmed to be operational with
this basic configuration. The missing GPIO and pinctrl support will be
added incrementally in future patches as the dependent subsystems become
available upstream.

damon_test_split_regions_of()
damon_test_split_regions_of() is assuming all dynamic memory allocation in
it will succeed. Those are indeed likely in the real use cases since
those allocations are too small to fail, but theoretically those could
fail. In the case, inappropriate memory access can happen. Fix it by
appropriately cleanup pre-allocated memory and skip the execution of the
remaining tests in the failure cases.
