exofs: Prints on mount and unmout
It is important to print in the logs when a filesystem was mounted and eventually unmounted. Print the osd-device's osd_name and pid the FS was mounted/unmounted on. TODO: How to also print the namespace path the filesystem was mounted on? Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
