Yes

kernel is 3.14.9-200.fc20.x86_64, if that is latest upstream, I don't know.
gluster is from master as of end of last week

If there are known issues with ext4 i could switch to something else, but during
the last 15 years or so, I have had very little problems with ext2/3/4, thats the 
reason for choosing it.
