Note, that inode_init_once() also does a memset on the entire inode, so the
initial memset is redundant on the inode portion. But I didn't think it was
really worth the time to complicate the code by optimizing it. I guess if I
changed the structure to:
struct tracefs_inode {
+ struct inode vfs_inode;
unsigned long flags;
void *private;
- struct inode vfs_inode;
};
I could have it do:
memset_after(ti, 0, vfs_inode);
But this can be done as a separate clean up and doesn't need to be done now.
