From 19fe294f2eaee33574ac1fdcf3cc26880de820ea Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Thu, 3 Sep 2009 20:38:02 +0300 Subject: 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?
