Feature #9557
Updated by Sage Weil over 9 years ago
Verify that the backtrace is valid when we finish fetch_dir. That is, that we would have been able to locate the dir inode. This should be basically free in terms of IO (an extra getxattr) and verifiable given the metadata we have in cache.
Make a config option to assert if the verification fails. Maybe another option to repair it when we see it.
