From bbd99797973f2cebd905bf6469ce08b531ab258f Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Thu, 30 Aug 2012 19:24:34 +0200 Subject: cuse: fix fuse_conn_kill() fuse_conn_kill() removed fc->entry, called fuse_ctl_remove_conn() and fuse_bdi_destroy(). None of which is appropriate for cuse cleanup. The fuse_ctl_remove_conn() decrements the nlink on the control filesystem, which is totally bogus. The others are harmless but unnecessary. So move these out from fuse_conn_kill() to fuse_put_super() where they belong.
