How can I reproduce this warning?  I am using the latest version of sparse, and
I don't see any of these warnings you're reporting.

$ sparse --version
v0.6.4
$ make C=2 fs/verity/
  CHECK   scripts/mod/empty.c
  CALL    scripts/checksyscalls.sh
  CALL    scripts/atomic/check-atomics.sh
  DESCEND objtool

  CHECK   fs/verity/hash_algs.c
  CHECK   fs/verity/init.c
  CHECK   fs/verity/measure.c
  CHECK   fs/verity/open.c
  CHECK   fs/verity/read_metadata.c
  CHECK   fs/verity/verify.c
