WineFS is a research persistent-memory filesystem that preserves hugepage-aligned extents through alignment-aware allocation and layout-preserving updates.
The artifact combines an aligned allocator with a hole-filling allocator and per-CPU journaling, building on PMFS. The pinned allocator separates aligned and unaligned free-space trees; a long free run alone does not describe its alignment class. [2] [3]
The prototype requires byte-addressable persistent memory and a modified Linux 5.1 kernel. Its strict and relaxed modes differ in data consistency, so mode belongs in any comparison. Hugepage use is a layout and address-translation property, not by itself proof of durable application updates. [2] [1]
