The dcache entries are allocated with SLAB_HWCACHE_ALIGN. For better
memory usage, we should increase DNAME_INLINE_LEN so that sizeof(struct
dentry) becomes a multiple of the L1 cache line size.

On i386 the DNAME_INLINE_LEN becomes 36 bytes instead of 16, which saves
thousands of kmallocs for external file names. (12818 on my debug
system, after updatedb)

The attached patch is preliminary, it doesn't compile with egcs-1.1.2.
Which gcc version added support for unnamed structures?
