Subject: holding a reference on an inode?
Date: Tue, 20 Apr 2004 20:28:16 -0400	[thread overview]
Message-ID: <1082507296.3133.4.camel@vertex> (raw)

Hello,

I am writing a kernel module, and I would like to allow user space to
hand me a FILE, and then for my kernel module to keep a reference on its
inode regardless what the user space program does with the FILE. 

1) Is this good practice?
2) How do I get notified when the filesystem the inode is on is being   
unmounted so I can release my reference? So that I don't block the
unmount.


I am not subscribed so please CC on my replies. 

Thank you.
