#     filldir[64]: remove WARN_ON_ONCE() for bad directory entries
#     
#     This was always meant to be a temporary thing, just for testing and to
#     see if it actually ever triggered.
#     
#     The only thing that reported it was syzbot doing disk image fuzzing, and
#     then that warning is expected.  So let's just remove it before -rc4,
#     because the extra sanity testing should probably go to -stable, but we
#     don't want the warning to do so.
#     
#     Reported-by: syzbot+3031f712c7ad5dd4d926@syzkaller.appspotmail.com
#     Fixes: 8a23eb804ca4 ("Make filldir[64]() verify the directory entry filename is valid")
