WasmVM: statvfs/fstatvfs not available in WASI #48
Description
Summary
statvfs() and fstatvfs() are not part of WASI Preview 1 — there is no filesystem statistics interface available. Programs calling these functions will fail.
Affected os-test cases
basic/sys_statvfs/statvfsbasic/sys_statvfs/fstatvfs
Category
wasi-gap — WASI Preview 1 does not expose filesystem statistics (block size, free blocks, etc.).
Notes
These were previously linked to issue #34 (stat metadata) which is a different issue. statvfs requires host-level filesystem information that the WASI sandbox does not provide.
