Aha. I found it. It seems the kernel Version is not correctly detected.
When i put #define u64_stats_fetch_begin_irq u64_stats_fetch_begin_bh #define u64_stats_fetch_retry_irq u64_stats_fetch_retry_bh right at the top of kcompat.h the module compiles just fine (i know - not advisable - but for the test). I see that there is already something for this in the source: #if (!( UBUNTU_VERSION_CODE && UBUNTU_VERSION_CODE >= UBUNTU_VERSION(3,13,0,30))) #define u64_stats_fetch_begin_irq u64_stats_fetch_begin_bh #define u64_stats_fetch_retry_irq u64_stats_fetch_retry_bh #endif I think all it needs it to make sure kernel versions are detected correctly.
