| |
The ->connected flag for a fuse_conn object previously only indicated whether the device file for this connection is currently open or not.
Change it's meaning so that it indicates whether the connection is active or not: now either umount or device release will clear the flag.
The separate ->mounted flag is still needed for handling background requests.
