Subject: dmsetup fails on latest kernel

Hi,

(subject added)

I rebased on the stop of latest mainline tree and now dmsetup fails...
It says: "Failed to create notification semaphore: Function not implemented".
I run strace and saw that dmsetup uses "semget" which returns -ENOSYS...

It works on
122804ecb59493fbb4d31b3ba9ac59faaf45276f

but does not work on
ccb19d263fd1c9e34948e2158c53eacbff369344

Any ideas?

- Dmitry
