Description Zdenek Kabelac 2013-10-17 07:30:26 UTC

Description of problem:

We may safe one call of dmsetup for splitname by merging this functionality with udevflags parsing - while it's breaking a bit of rules spliting by doing dm-lvm part in dm rules - it could be a win in terms of CPU usage and udev rule processing speed when a lot of devices are in use.

Should be probably at least measured if this optimization is worth to make.

Alternatively, we can suggest these helper functions to be a part of udev builtin command set - these are really simple so udev team could accept the patch.
