| udiskslinuxmountoptions-do-not-free-static-daemon-resources.patch | [PATCH] udiskslinuxmountoptions: Do not free static daemon resources The GResource instance returned from udisks_daemon_resources_get_resource() that calls g_static_resource_get_resource() internally is marked as '(transfer none)' and should not be freed. In fact that causes double free inside the g_static_resource_fini() atexit handler leading to memory corruption causing random failures of further atexit handlers such as cryptsetup and openssl destructors.
