Subject: [PATCH 2/2] bcache: fix inaccurate result of unused buckets
Date: Tue,  5 Mar 2019 07:07:33 -0500	[thread overview]
Message-ID: <1551787653-3115-1-git-send-email-fangguoju@gmail.com> (raw)

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.
