SELinux: inode_doinit_with_dentry drop no dentry printk (df7f54c0) · Commits · 戴 / test

Drop the printk message when an inode is found without an associated dentry. This should only happen when userspace can't be accessing those inodes and those labels will get set correctly on the next d_instantiate. Thus there is no reason to send this message. Signed-off-by:
