2007-02-12[PATCH] mark struct file_operations const 8Arjan van de Ven31-51/+51
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-12[PATCH] knfsd: SUNRPC: Provide room in svc_rqst for larger addressesChuck Lever2-8/+14
Expand the rq_addr field to allow it to contain larger addresses. Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then everywhere the 'sockaddr_in' was referenced, we use instead an accessor function (svc_addr_in) which safely casts the _storage to _in.

Top among these are error and debugging messages that display the server's IP address.

Rather than calling svc_sock_enqueue at the end of svc_setup_socket, we now call it (via svc_sock_recieved) after calling svc_setup_socket at each call site.

2007-02-10[UDP]: UDP can use sk_hash to speedup lookupsEric Dumazet2-6/+7
In a prior patch, I introduced a sk_hash field (__sk_common.skc_hash) to let tcp lookups use one cache line per unmatched entry instead of two. We can also use sk_hash to speedup UDP part as well. We store in sk_hash the hnum value, and use sk->sk_hash (same cache line than 'next' pointer), instead of inet->num (different cache line) Note : We still have a false sharing problem for SMP machines, because sock_hold(sock) dirties the cache line containing the 'next' pointer.
