Commit Message

Dr. David Alan Gilbert Oct. 26, 2020, 6:43 p.m. UTC 
From: Max Reitz <mreitz@redhat.com>

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.
