Multigrain Timestamps Try Again For Linux 6.13 - Now With Less Performance Impact
20 November 2024 - VFS Multigrain Timestamps

Merged last year for Linux 6.6 was multi-grain(ed) timestamps to address the current coarse-grained timestamps when updating creation time and modification time that a lot of I/O activity can happen in the once-per-jiffy timestamp. Just a few weeks in the Linux 6.6 kernel, multi-grain timestamps were removed due to bugs. The multigrain code went back to be reworked and now just over one year later the code has been re-merged into the mainline Linux kernel.
