Hi! Can't we just resolve this by patching
#elif defined(__aarch64__) #include <linux/simd_aarch64.h> out of include/os/linux/kernel/linux/simd.h in the zfs modules source and thus forcing the use of: #else #define kfpu_allowed() 0 #define kfpu_begin() do {} while (0) #define kfpu_end() do {} while (0) #define kfpu_init() 0 #define kfpu_fini() ((void) 0) #endif #endif /* _LINUX_SIMD_H */ at the end of the file? Any regressions should be caught by the ZFS test suite.... --OR-- we just mark zfs-linux package and zfsutils-linux incompatible with ARM64/__aarch64__ architecture in the debian packages... Thoughts???? Cheers, Matt Grant
