| H A D | namei.c | cbae4d12 Sun Jan 12 12:40:02 CST 2020 Al Viro <viro@zeniv.linux.org.uk> fold handle_mounts() into step_into()
The following is true:
* calls of handle_mounts() and step_into() are always
paired in sequences like
err = handle_mounts(nd, dentry, &path, &inode, &seq);
if (unlikely(err < 0))
return err;
err = step_into(nd, &path, flags, inode, seq);
* in all such sequences path is uninitialized before and
unused after this pair of calls
* in all such sequences inode and seq are unused afterwards.
So the call of handle_mounts() can be shifted inside step_into(),
turning 'path' into a local variable in the combined function.
