Hi, Here is the V8 of the patches. Primarily I have taken care of comments from Amir. This applies on top of the fix I posted with subject "ovl: Pass ovl_get_nlink() parameters in right order" Amir, I have added one more patch int series where I pass index dentry to ovl_get_nlink() to get rid of a warning during testing. I think only outstanding concern with this patch series now is how to detect that metacopy feature was ever enabled and there are some metacopy only files present. In that case we probably don't want to allow user to mount with metacopy=off. We currently don't seem to have a generic infrastructure which keeps track of features and backward compatibility stuff etc. Discussion still seems to be on upstream. Is this a blocker for this patch series or this is something we can live with? Only downside of mounting a file system which has metacopied files (with metacopy=off), is that user will see truncated files.
