2005-06-22[PATCH] RPC: kick off socket connect operations fasterChuck Lever
Make the socket transport kick the event queue to start socket connects immediately. This should improve responsiveness of applications that are sensitive to slow mount operations (like automounters). We are now also careful to cancel the connect worker before destroying the xprt. This eliminates a race where xprt_destroy can finish before the connect worker is even allowed to run. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. Hard-code impossibly small connect timeout.

2005-06-22[PATCH] RPC: TCP reconnects are too slowChuck Lever
When the network layer reports a connection close, the RPC task waiting to reconnect should be notified so it can retry immediately instead of waiting for the normal connection establishment timeout. This reverts a change made in 2.6.6 as part of adding client support for RPC over TCP socket idle timeouts. Test-plan: Destructive testing with NFS over TCP mounts.

2005-06-22[PATCH] RPC: Ensure rpc calls respects the RPC_NOINTR flagTrond Myklebust
For internal purposes, the rpc_clnt_sigmask() call is replaced by a call to rpc_task_sigmask(), which ensures that the current task sigmask respects both the client cl_intr flag and the per-task NOINTR flag. Problem noted by Jiaying Zhang. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] RPC: Allow the sunrpc server to multiplex serveral programs on a ↵Andreas Gruenbacher

2005-06-22[PATCH] RPC: [PATCH] improve rpcauthauth_create error returnsJ. Bruce Fields
Currently we return -ENOMEM for every single failure to create a new auth. This is actually accurate for auth_null and auth_unix, but for auth_gss it's a bit confusing. Allow rpcauth_create (and the ->create methods) to return errors. With this patch, the user may sometimes see an EINVAL instead. Whee. Signed-off-by: J.

support Ensure that we don't create an RPC client without checking that the server does indeed support the RPC program + version that we are trying to set up.

2005-06-22[PATCH] RPC: Fix a race with rpc_restart_call()Trond Myklebust

2005-05-01[PATCH] DocBook: changes and extensions to the kernel documentationPavel Pisa
I have recompiled Linux kernel 2.6.11.5 documentation for me and our university students again. The documentation could be extended for more sources which are equipped by structured comments for recent 2.6 kernels. I have tried to proceed with that task. I have done that more times from 2.6.0 time and it gets boring to do same changes again and again. Linux kernel compiles after changes for i386 and ARM targets. I have added references to some more files into kernel-api book, I have added some section names as well. So please, check that changes do not break something and that categories are not too much skewed. I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved by kernel convention. Most of the other changes are modifications in the comments to make kernel-doc happy, accept some parameters description and do not bail out on errors. Changed <pid> to @pid in the description, moved some #ifdef before comments to correct function to comments bindings, etc. You can see result of the modified documentation build at http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz Some more sources are ready to be included into kernel-doc generated documentation. Sources has been added into kernel-api for now. Some more section names added and probably some more chaos introduced as result of quick cleanup work.

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!
