Are you looking for operations performed on a path provided or the
directory subtree under that path too?
io-stats maintains statistics of a few operations performed on file
along with the fd/inode. For directories, I don't see much statistics collected.
One big gap in io-stats is that there is no interface to peek at a small subset
of the entire statistics collected. I am wondering if we could use the
help of meta xlator to provide these interfaces.
