[f2fs-dev] [PATCH] f2fs: introduce hot_data_age_threshold and warm_data_age_threshold mount opt

This patch supports parsing these two parameters from mount opt, so that we don't have to dynamically modify the parameters through the sysfs node after the system starts. Signed-off-by: Yangtao Li --- Documentation/filesystems/f2fs.rst | 6 + fs/f2fs/debug.c| 3 ++-

[f2fs-dev] [PATCH 6/6] f2fs: add block_age-based extent cache

This patch introduces a runtime hot/cold data separation method for f2fs, in order to improve the accuracy for data temperature classification, reduce the garbage collection overhead after long-term data updates. Enhanced hot/cold data separation can record data block update frequency as "age" of

[f2fs-dev] [PATCH] f2fs: fix iostat parameter for discard

Just like other data we count uses the number of bytes as the basic unit, but discard uses the number of cmds as the statistical unit. In fact the discard command contains the number of blocks, so let's change to the number of bytes as the base unit. Fixes: b0af6d491a6b ("f2fs: add app/fs io
