[dm-devel] locking optimization



A few month ago a lock-to-RCU conversion patch was posted:

http://www.spinics.net/lists/dm-devel/msg19111.html

Any chances that it will make it into mainline?

We did some measurements and love it :-)

Without that optimization dm_get_live_table() stands out as the most
expensive dm-mod function. With that optimization the CPU cycles
consumed by dm_get_live_table() are reduced dramatically.

Cheers,
Martin
