[$] Flexible data placement

Date:
Fri, 02 May 2025 17:51:48 +0000

Description:
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.
