That's not how lockdep_assert_held() is used in the kernel. This macro
is more often than not used to document assumptions that can be verified
at compile time.

This patch seems like a step in the wrong direction to me because it
*suppresses* compile time analysis compile-time analysis is useful. I
think that this patch either should be dropped or that the __assume()
annotations should be changed into __must_hold() annotations.
