The first two patches are fixes. The last two are for userspace raid6test support on RISC-V. The issue fixed in patch 2/4 was probably the same which was spotted by Charlie [1], I couldn't reproduce it at that time. When running raid6test in userspace on RISC-V, I saw a segmentation fault, I used gdb command to print pointer p, it was an unaccessible address.
Can you give me your config, kernel and toolchain versions? I can't reproduce the segfault on my machine.
Thanks for the fixes and the test, I'll take a look this week. Alex
With patch 2/4, the issue didn't appear anymore.
