Detailed Description

This simple slab cache emulation was introduced for the Linux USB drivers.

There are some limitations/constraints:

• the size of slab-objects is restricted to L4_PAGESIZE (because of l4slab)
• name, flags, dtor of slab caches are ignored

Requirements: (additionally to Global Requirements)

• L4Env slab library (libslab.a)

It's from mm/slab.c.

constraints:

• max size L4_PAGESIZE
• name, flags, dtor are ignored
