[PATCH 02/18] bcache: fix inaccurate result of unused buckets

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

 



From: Guoju Fang <fangguoju@xxxxxxxxx>

To get the amount of unused buckets in sysfs_priority_stats, the code
count the buckets which GC_SECTORS_USED is zero. It's correct and should
not be overwritten by the count of buckets which prio is zero.
