From b507cbc2b1aaec1931642497edcb6723a0d24dc4 Mon Sep 17 00:00:00 2001 From: Joanne Koong Date: Fri, 23 Aug 2024 13:11:09 -0700 Subject: Add statx support This commit adds libfuse support for FUSE_STATX requests on linux distributions. Currently, statx is only supported on linux. To make the interface a ergonomic as possible (eg using native 'struct statx' vs 'struct fuse_statx'), this implementation gates the 'struct statx' changes by #ifdef linux.
