[patch] vfs: make security_inode_setattr() calling consistent

[Miklos Szeredi]

From: Miklos Szeredi <mszeredi@xxxxxxx>

Call security_inode_setattr() consistetly before inode_change_ok().
It doesn't make sense to try to "optimize" the i_op->setattr == NULL
case, as most filesystem do define their own setattr function.
