Move writeback-related functions and data structures from zram_drv.[ch] to a new zram_wb.[ch] file. This is a pure refactoring patch with no functional changes, preparing the ground for the upcoming asynchronous writeback implementation. Signed-off-by: Richard Chang <[email protected]>
Introduce the necessary infrastructure for performing writeback operations asynchronously. It adds a dedicated kernel thread (`zram_wb_thread`), a request queue for managing pending writebacks, and helper functions to deal with the writeback requests. This patch lays the foundation for enabling asynchronous writeback in a subsequent change. Signed-off-by: Richard Chang <[email protected]>

Upstream branch: b19a97d |
Replace the synchronous `submit_bio_wait()` with the non-blocking `submit_bio()` to perform writeback operations asynchronously. This leverages the infrastructure added in the previous commit to handle the completion of I/O operations in a dedicated kthread. This change shows 27% speed improvement of idle writeback on Android platform. Test Flow: - mkfs on the zram device, mount it - cp three linux-6.16-rc2.tar.gz tarball files as the data - do idle writeback - check bd_stat writes 185072 pages Test Result: idle writeback for 185072 4k-pages (~723 MiB) $ echo all > /sys/block/zram0/idle $ time echo idle > /sys/block/zram0/writeback Async writeback: 0m02.49s real 0m00.00s user 0m01.19s system 0m02.32s real 0m00.00s user 0m00.89s system 0m02.35s real 0m00.00s user 0m00.93s system 0m02.29s real 0m00.00s user 0m00.88s system Sync writeback: 0m03.09s real 0m00.00s user 0m01.07s system 0m03.18s real 0m00.00s user 0m01.12s system 0m03.47s real 0m00.00s user 0m01.16s system 0m03.36s real 0m00.00s user 0m01.27s system Signed-off-by: Richard Chang <[email protected]>
