[PATCH] Reduce sched latency in shrink_dcache_sb()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch reduces scheduling latency in shrink_dcache_sb()
noticed during remounting of big partitions with many cached dentries.
The same latency fix was applied to select_parent() long ago.
