+// The format of the stat cache is (pseudo-code):
+// struct stat_cache {
+// char Magic[4]; // "STAT" or "Stat"
----------------
Few comments about stats representation.
1. Can we version the stat cache file so we can evolve it in the future if
needed?
2. I wonder if we need to have a more flexible representation for DataType
other than `sys::fs::file_status`. Current entry is locked with the endian of
the host and can't be used to encode more information than file_status.
