In a previous commit bb0838b511, the gc_urgent_sleep_time for F2FS was aggressively set to 50ms to optimize GC.
This change, however, led to performance regressions on most devices, particularly of those running in 4.19+ kernels.
From our tests, the heightened CPU and I/O activity from this aggressive garbage collection setting is the likely cause.
To address this, we're revising the gc_urgent_sleep_time parameter to strike a balance between aggressive GC and device performance, taking
bb0838b511 goal into consideration.
Furthermore, the dirty writeout policy has been aligned with the latest configurations used in Pixel devices,
and cp_interval has been adjusted to surpass dirty_expire_centisecs for improved power efficiency during idle times.
Test: booted partner device, monitor performance
