[Devel] [PATCH 01/15] fs/fuse: add conn_ctl to fuse_conn struct

[Pavel Butsykin]

This is preparation patch that places sysfs dentry pointer to fc that's
created for each mount point. This will be necessary for forwarding KIO
statistics through sysfs, that will also need to be done separately for each
mount point.
