Patch series "GDB VFS utils". I've created a couple GDB convenience functions that I found useful when debugging some VFS issues and figure others might find them useful. For instance, they are useful in setting conditional breakpoints on VFS functions where you only care if the dentry path is a certain value. I took the opportunity to create a new "vfs" python module to give VFS related utilities a home. This patch (of 2): This will allow for more VFS specific GDB helpers to be collected in one place. Move utils.dentry_name into the vfs modules. Also a local variable in proc.py was changed from vfs to mnt to prevent a naming collision with the new vfs module.
