Subject: [PATCH] Fix the broken cache more.
Take a look at the nano second in the mtime to figure out
if the cache needs to be updated if available.
and do the mutex lock between scanning and writing a cache
to avoid the conflict.
Also we don't need to scan directories again after writing
caches. so getting rid of the related code as well.
