newsize = newsize + CONFIG_FS_TMPFS_FILE_ALLOCGUARD;
When newsize is a large value,
adding a relatively small value can cause the result to become very small,
resulting in program logic errors.
For example:
0xffffffff + 0x2 = 1

There are ICs available on the market that integrate various power inverter
features. The driver for such a device must be tightly coupled to a FOC device
as using it as a separate device doesn't make sense.
Adds support for hardware timestamping of received Ethernet packets.
The timestamp is available to applications using socket option SO_TIMESTAMP.
Optionally, the Ethernet PTP timer can be used as system high-resolution RTC.
In this mode it supports fine resolution rate adjustment.
Alternatively other time source for CLOCK_REALTIME can be used, and the
PTP timestamps are converted by sampling the clocks and computing the
difference. This results in a few microseconds of uncertainty.
Adds support for timestamping received UDP packets, either in
hardware or in kernel. Builds on the existing support of SO_TIMESTAMP
for SocketCAN.
Implementation uses CLOCK_REALTIME for timestamping to match the
behavior of Linux. This could be made configurable in future if needed.
The halt operation may be causes the raw epread data segment lost, and
usb ep_queue can handle when the usb buffer is full. so remove the
relevant operations.

Enable CONFIG_DEV_SIMPLE_ADDRENV for all the qemu configs that used
the virtio driver to fix compile error when use the NuttX implemented
metal io read/write operations.
Becasue up_addrenv_pa_to_va() and up_addrenv_va_to_pa() are not
implemented by default.

Openamp/libmetal's metal io operation used the atomic operation, but
in QEMU 8.1.2, the risc-v IO region is not allow to use atomic instruction
in SMP case.

The task files should consult the "spawn action" and "O_CLOEXEC flags"
to determine further whether the file should be duplicated.
This PR will further optimize file list duplicating to avoid the performance
regression caused by additional file operations.
