Hey John... it's Jihn Strange... funny meeting you here on dm-devel. So your playing around with dm, huh?  I did a few months ago. I like the architecture, as you're seeing, the implementation lacks dicipline.  Hope things are going well for you guys at RSC.

Solved my own issue methinks, the name of the module that i am finding in drivers/md/ is linear.ko, not dm-linear.ko. that was unexpected. i note further that there are other non 'dm- decorated' lkms in md as well, such as multipath, faulty, raid0, etc.

is there an implication associated with things decorated with dm- vs things not decorated with dm- in the md directory?

tnx!

Hello;

I have a linear device that i am attempting to harness to device mapper.

My expectation that i developed based on my reading was that I could start from a dm-linear.c => dm-linear.ko and go from there.

But dm-linear.c gets linked into dm-mod.ko, not dm-linear.ko.

Has dm-linear always been part of dm-mod? i see some stuff on the net that implies the existence of dm-linear.ko, but i have poked around in menuconfig and i can find no specific entry to create it.

Any suggestions as to how to proceed would be greatly appreciated.

tnx!

johnu
