At
the 2025 Linux Storage, Filesystem, Memory
Management, and BPF Summit (LSFMM+BPF) Kanchan Joshi and Keith Busch led a combined storage and filesystem session on data placement, which concerns
how the data on a storage device is actually written. In a discussion
that hearkened back to previous summits, the idea is to give hints to enterprise-class
SSDs to help them make better choices on where the data should go; hinting
was most recently discussed at the summit in 2023. If SSDs can
group data with similar lifetimes together, it can lead to longer life for
the devices, but there is a need to work out the details.
