Subject: [PATCH v2] bcache: fixup init dirty data errors
Date: Thu, 24 Aug 2023 20:57:30 +0800 [thread overview]
Message-ID: <20230824125730.3273-1-mingzhe.zou@easystack.cn> (raw)
We found that after long run, the dirty_data of the bcache device
will have errors. This error cannot be eliminated unless re-register.
We also found that reattach after detach, this error can accumulate.
In bch_sectors_dirty_init(), all inode <= d->id keys will be recounted
again. This is wrong, we only need to count the keys of the current
device.
Fixes: b144e45fc576 ("bcache: make bch_sectors_dirty_init() to be multithreaded")
