[PATCH] remove unused blkp field in percpu_data
I found that blkp field was not used in kernel tree. As most of the times NR_CPUS is a power of two and kmalloc() memory blocks too, this extra field basically doubles the memory space allocated in __alloc_percpu() to store the 'struct percpu_data' (for example, if NR_CPUS=8 on i386, kmalloc(4*8+4) returns a 64 bytes block instead of a 32 bytes block after this patch) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
