Hi all, I know you dont like it, but i need to get the device id as it appear in user space from kernel space. i know its anonymous device id and i should not get it. but i still need it.
I found there are 2 ways to get it: 1. cast inode to btrfs_inode and get it from btrfs_inode->root->anon_dev 2. from dentry object: dentry->d_inode->i_op->getattr(NULL, dentry,kstat); There is a problem ! Usually what I do on file system event is to take the dentry->d_inode-... everything works fine. BUT on rename operations, the signature for vfs_rename is dual of inode-struct: (struct inode *, struct dentry *,struct inode *, struct dentry *, unsigned int) So what i do is take the 2nd dual dentry struct (destination dentry), and when i look for d_inode, there is no inode. And if i take the 2nd dual inode parameter from the vfs_rename function and try to call it inode->i_op->getattr(...) with the 2nd dual dentry -> I get btrfs_getattr exception. Is there a solution ?
