Subject: [PATCH net-next v3 0/8] rust: Add IO polling
polls periodically until a condition is met or a timeout is reached.
By using the function, the 8th patch fixes QT2025 PHY driver to sleep
until the hardware becomes ready.
As a result of the past discussion, this introduces a new type
representing a span of time instead of using core::time::Duration or
time::Ktime.
Unlike the old rust branch, This adds a wrapper for fsleep() instead
of msleep(). fsleep() automatically chooses the best sleep method
based on a duration.
v3:
- Update time::Delta methods (use i64 for everything)
- Fix read_poll_timeout to show the proper debug info (file and line)
- Move fsleep to rust/kernel/time/delay.rs
- Round up delta for fsleep
- Access directly ktime_t instead of using ktime APIs
- Add Eq and Ord with PartialEq and PartialOrd
v2: https://lore.kernel.org/lkml/20241005122531.20298-1-fujita.tomonori@gmail.com/
- Introduce time::Delta instead of core::time::Duration
- Add some trait to Ktime for calculating timeout
- Use read_poll_timeout in QT2025 driver instead of using fsleep directly
v1: https://lore.kernel.org/netdev/20241001112512.4861-1-fujita.tomonori@gmail.com/
