F2FS 在 Linux 7.0 中带来多项性能优化

F2FS 在 Linux 7.0 中带来多项性能优化 ⚡

F2FS（Flash-Friendly File System）是专为 NAND 闪存（SSD、eMMC、UFS 等）设计的日志结构文件系统。在 Linux 7.0 开发周期内，F2FS 合并了多项性能改进，为用户提供了更好的体验。
🔹 引入了引入大 folio 支持，以提高不可变文件的读取速度。
🔹 通过仅刷新已提交的脏页来减少 checkpoint=enable 的延迟。
🔹 实施跟踪点以诊断和解决锁优先级反转问题。
🔹 引入了 packed_ssa 特性，以在使用大区块大小时优化 SSA 的内存占用。
🔹 通过对检查点写入的优化，在现已合并的补丁中，刷新时间从 158 毫秒降至 11 毫秒。
💭 除了多项修复外，Linux 7.0 的 F2FS 更新整体看来相当不错。
