  If you forgot to add the Reported-by tag, once the fix for this bug is merged into any tree, please reply to this email with:
  #syz fix: exact-commit-title 

? That's the reason I keep

  KASAN: use-after-free Read in fuse_kill_sb_blk
  https://syzkaller.appspot.com/bug?id=a07a680ed0a9290585ca424546860464dd9658db

report "open()" table but I want keyword column available in the "open()" table
so that we can announce that "patch is proposed and waiting for review" state.
