* [PATCH] mark struct file_operations const 7Arjan van de Ven2007-02-12
| | | | | | | | | | | 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.

* [DECnet]: Endian annotation and fixes for DECnet.Steven Whitehouse2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | The typedef for dn_address has been removed in favour of using __le16 or __u16 directly as appropriate. All the DECnet header files are updated accordingly. The byte ordering of dn_eth2dn() and dn_dn2eth() are both changed since just about all their callers wanted network order rather than host order, so the conversion is now done in the functions themselves. Several missed endianess conversions have been picked up during the conversion process. The nh_gw field in struct dn_fib_info has been changed from a 32 bit field to 16 bits as it ought to be. One or two cases of using htons rather than dn_htons in the routing code have been found and fixed. There are still a few warnings to fix, but this patch deals with the important cases.

* [NET]: Add a dev_ioctl() fallback to sock_ioctl()Christoph Hellwig2006-01-03
| | | | | | | | | | | Currently all network protocols need to call dev_ioctl as the default fallback in their ioctl implementations. This patch adds a fallback to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD. This way all the procotol ioctl handlers can be simplified and we don't need to export dev_ioctl.

* [NET]: move struct proto_ops to constEric Dumazet2006-01-03
| | | | | | | | | | | | | | | | | | | | | | 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.

* [DECNET]: fix SIGPIPEPatrick Caulfield2005-11-11
| | | | | | | | | | | Currently recvmsg generates SIGPIPE whereas sendmsg does not; for the other stacks it seems to be the other way round!

* [PATCH] gfp flags annotations - part 1Al Viro2005-10-08
| | | | | | | | | | | | - added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

* [NET]: Kill skb->real_devDavid S. Miller2005-08-29
| | | | | | | | | | | Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument.

* [NET]: Kill skb->listDavid S. Miller2005-08-29
| | | | | | | | | | | | | | Remove the "list" member of struct sk_buff, as it is entirely redundant. All SKB list removal callers know which list the SKB is on, so storing this in sk_buff does nothing other than taking up some space.

* [NET]: Transform skb_queue_len() binary tests into skb_queue_empty()David S. Miller2005-07-08
| | | | | | | | | | | | | This is part of the grand scheme to eliminate the qlen member of skb_queue_head, and subsequently remove the 'list' member of sk_buff. Most users of skb_queue_len() want to know if the queue is empty or not, and that's trivially done with skb_queue_empty() which doesn't use the skb_queue_head->qlen member and instead uses the queue list emptyness as the test.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
