From 97d741cc96dd08b183cb098a38d55b641e277be0 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Wed, 9 Sep 2020 20:40:21 +0200 Subject: linux/fuse.h: Pull in from Linux Update the linux/fuse.h standard header from the kernel development tree that implements FUSE submounts. This adds the fuse_attr.flags field, the FUSE_ATTR_FLAGS INIT flag, and the FUSE_ATTR_SUBMOUNT flag for fuse_attr.flags.
