+Subject: [PATCH] Fix loading of FUSE modules
+
+dlsym returns the address of the module factory symbol, not the actual function (#722)
+pointer. Change the type of `factory` to `fuse_module_factory_t*` to reflect
+this and then dereference it when registering the module.
+
+This is a followup to d92bf83, which introduced a NULL pointer dereference
+when dlsym returns NULL, and 8ec7fd9, which reverted it back to not
+dereferencing the symbol at all.
+
+Fixes: #721
