Subject: Re: [PATCH] fs: inode per-cpu last_ino allocator

Eric,

what workload did this matter for?  As mentioned elsewhere we don't
actually need to set i_ino in new_inode in many cases.  Normal
disk/network filesystem already set their own i_ino anyway and don't
need it at all.  Various in-kernel filesystems don't need any valid
i_ino and Nick's full series actually has a patch dealing with it,
which only leaves various user-mountable syntetic filesystems that
want to generate an inode number, and IMHO they're better off using
iunique.
