Hi All,
Not sure if it has been reported, builds of arm64 with clang failed to
build next-20220811 with the error:
drivers/vdpa/vdpa_sim/vdpa_sim_blk.c:201:3: error: expected expression

8 errors generated.
git bisect pointed to d79b32c2e4a4 ("vdpa_sim_blk: add support for discard and write-zeroes").
And, reverting that commit has fixed the build failure.
I will be happy to test any patch or provide any extra log if needed.
