I was looking for that backport, but could not find it. But that backport was done way long ago... And given the discussion in the PR, backporting was bit of a struggel
But I think I see the problem.... The original PR touched 14 files.
The backport only touches 13 files...
And fixing src/test/libcephfs/lazyio.cc for the sysxattr.h file got left out.
And I turned building cephfs stuff on in the Jenkinss builder only like last week on Nautilus because I wanted to get ride of Dashboard complaints about missing the cephfs module.
So what is the easiest way to fix that.
Open a PR targeting nautilus. Include a sentence in your commit statement that starts with the words "This fix cannot be backported from master because . . . ." Feel free to ping me in the PR. Nathan
