So the *test* they run is asking device-mapper to briefly reserve a 64KB
buffer when there is no data to report: The answer is not to run that
pointless test:)
And if a single 64KB allocation really is a big deal, then patch 'vold'
in userspace so it doesn't ask for 64KB when it clearly doesn't need it!
+ int Devmapper::dumpState(SocketClient *c) {
+ char *buffer = (char *) malloc(1024 * 64);
The code has just
#define DEVMAPPER_BUFFER_SIZE 4096
for all the other dm ioctls it issues.
Only use a larger value when it is needed i.e. if DM_BUFFER_FULL_FLAG gets set.
