Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

However, the length argument turns out to be superfluous. I was just reading ipv6_skip_exthdr and it occured to me that we can get rid of len altogether. The only place where len is used is to check whether the skb has two bytes for ipv6_opt_hdr. This check is done by skb_header_pointer/skb_copy_bits anyway. Now it might appear that we've made the code slower by deferring the check to skb_copy_bits. However, this check should not trigger in the common case so this is OK.

[INET6]: Generalise tcp_v6_hash_connect Renaming it to inet6_hash_connect, making it possible to ditch dccp_v6_hash_connect and share the same code with TCP instead. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[NET]: move struct proto_ops to const I noticed that some of 'struct proto_ops' used in the kernel may share a cache line used by locks or other heavily modified data. (default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
