Is there anything in the filesystem control blocks to indicate that a file is open for write/update? A routine to read a linux filesystem from VM or OS could have a special return code for 'Yes, I can find it, but someone else is writing it'. Then it would be up to the user to decide to stop or continue with a possible data integrity exposure.
