[Gluster-users] False notifications

[Milos Kozak]

Thank you,

I tried to search on website but I could not find any release date for 
3.5.1. Do you have any expectation or where I could find a bit more 
about that?

Thanks

There are still some corner cases for metadata (ownership/permissions etc), entry (create/unlink/rename/mkdir/rmdir/symlink/link) operations where it may show them in the output even though it is just I/O.
