[INET]: Shrink struct inet_ehash_bucket on 32 bits UP
No need to align struct inet_ehash_bucket on a 8 bytes boundary. On 32 bits Uniprocessor, that's a waste of 4 bytes per struct (50 %) On other platforms, the attribute is useless, natual alignement is already 8. platform | Size before | Size after patch -------------+-------------+------------------ 32 bits, UP | 8 | 4 32 bits, SMP | 8 | 8 64 bits, UP | 8 | 8 64 bits, SMP | 16 | 16 Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
