Let's ask the same question in a different way: A quick search for 'vold' returns: https://android.googlesource.com/platform/system/vold/ and the code there requests a fixed 64K allocation to hold the names of active volumes.
So unlike libdevmapper-based applications where a smaller allocation is used at first and only extended if needed, Android just assumes that 64KB is enough for everyone. So is your claim that: 1. This 64KB allocation for the brief duration of the ioctl to store the names of active device-mapper volumes leads to memory problems? [Mustn't the system *already* be in a bad state if this pushes it over the limit?] and 2. The systems on which this memory shortage occurs have so many volumes (with long names?) that a smaller allocation would not suffice?
