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)

Function Documentation

kmem_cache_t* kmem_cache_create (  const char *  name, size_t  size, size_t  offset, unsigned long  flags, void(*  ctor)(void *, kmem_cache_t *, unsigned long), void(*  dtor)(void *, kmem_cache_t *, unsigned long) )

Create slab cache. It's from mm/slab.c constraints: max size L4_PAGESIZE name, flags, dtor are ignored Definition at line 96 of file slab.c. References alloc_grow(), DEBUG_SLAB, and vmalloc().
