From: Guoju Fang <fangguoju@gmail.com> mainline inclusion from mainline-5.2-rc1 commit 4e0c04ec3a304490a83d5c0355e64176acc9b4ba category: backport 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.
