No, not yet. I had those bad experiences with xfs_fsr on a ck patchset
patched kernel and after this I didn't try again. Its pretty sure that my
file content corruption issues was related to the ck patchset as I was
not able to reproduce it with a CFS or mainline kernel. But still I have
been reluctant. I think, I give it a try after I made my backups.
