Subject: is the inode an orphan?
Date: Thursday, October 18, 2007 - 1:49 pm

Hi,

I need a help from VFS folks: when I'm in ->unlink() in is there a safe way to 
to realize that ->delete_inod()e is going to be called? IOW, I'd like to call 
myfs_delete_inode() myself form ->unlink(), and not wait for VFS calling 
->delete_inode().

Or to put it differently, I'd like to know if the inode is an orphan or not in 
->unlink()?

AFAICS, if (inode->i_nlink == 0 && atomic_read(&inode->i_count) == 2) then this 
  file is not going to be an orphan. And AFAIC judge, it is safe to use this, 
but I'm not sure and kindly ask for help.

Thanks.
