+Subject: [PATCH] Use destroy_req instead of free to destroy fuse_req
+
+If we get the interrupt before the fuse op, the fuse_req is deleted without
+decrementing the refcount on the cloned file descriptor. This leads to a
+leak of the cloned /dev/fuse file descriptor.

+
+It's a false positive,  I thinks.  But it's also easy to silence this
+warning with a small refactor.
