Comment 67 for bug 344878

Jakob,

it can be a lot of extra seeks, but it is only done for entries that are long names, which are hopefully the exception. Unfortunately this is the case for any method we use to store long name information that doesn't fit in the underlying file system dentry (special dentry file, file header, xattr).

I have some more updates/alternatives coming for this patch, and will post some test kernels once the new versions are ready.
