From 4181e8c97482a3c787c2b508e6d75a21323ba515 Mon Sep 17 00:00:00 2001 From: Craig Chi Date: Wed, 9 Sep 2020 09:16:09 -0700 Subject: Add fh support for revise attr and fstat(2) test According to Linux 4.4's FUSE behavior, the flags and fh attributes in FUSE_GETATTR are only used in read, write, and lseek. fstat(2) doesn't use them either. Add tests to ensure the requests sent from FUSE module are consistent with Linux's.
