for_each_alias(): helper macro for iterating through dentries of given inode
Most of the places using d_alias are loops iterating through all aliases for
given inode; introduce a helper macro (for_each_alias(dentry, inode))
and convert open-coded instances of such loop to it.
They are easier to read that way and it reduces the noise on the next steps.
You _must_ hold inode->i_lock over that thing.
