# \[PATCH v2 2/5\] fs: Use a percpu\_counter to track nr\_inodes - From: Eric Dumazet \ - Date: 2008-11-29 08:43:39 - List: netdev - Page: https://ratatoskr.run/netdev/2008/11/27587 - Thread: https://ratatoskr.run/linux-fsdevel/2008/11/27587/t.md ```text Avoids cache line ping pongs between cpus and prepare next patch, because updates of nr_inodes dont need inode_lock anymore.
