[fedfs-utils] [PATCH 2/8] fedfsd: don't return freed memory through **pathname parameter, ...

[Jim Meyering]

From: Jim Meyering <meyering at redhat.com>

even though upon error it will not be used.
* src/fedfsd/svc.c (fedfsd_pathwalk): On an error path, don't
set *pathname at all, and certainly not to a just-freed pointer.

mount avoid one-byte heap-write overrun
