This is allocating memory for a RAM disk which will persist for the life of the system. RTEMS has no "de-initialize" driver call so there is no corresponding free(r).

Later this was closed as "Ignore"/"Intentional"

Though I agree that closing this CID this way is appropriate,
I think this actually needs fixing in longer term.

Context:
cpukit/libblock/src/ramdisk-config.c:
...
ramdisk_initialize()
...
Event alloc_fn: Calling allocation function "calloc".
Event var_assign: Assigning: "r" = storage returned from "calloc(rtems_ramdisk_configuration_size, sizeof (struct ramdisk) /*16*/)".
49 r = calloc(rtems_ramdisk_configuration_size, sizeof(struct ramdisk));
50 r->trace = false;
...
Event leaked_storage: Variable "r" going out of scope leaks the storage it points to.
89 return RTEMS_SUCCESSFUL;

You can create removable drivers now with:
