* [PATCH] fs: Conversions from kmalloc+memset to k(z|c)allocPanagiotis Issaris2006-09-271-2/+2
| | | | | | | | | Conversions from kmalloc+memset to kzalloc. Signed-off-by: Panagiotis Issaris <takis@issaris.org> Jffs2-bit-acked-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* LOCKD: Convert to use new rpc_create() APIChuck Lever2006-09-221-23/+27
| | | | | | | | | | | | | | | Replace xprt_create_proto/rpc_create_client with new rpc_create() interface in the Network Lock Manager. Note that the semantics of NLM transports is now "hard" instead of "soft" to provide a better guarantee that lock requests will get to the server. Test plan: Repeated runs of Connectathon locking suite. Check network trace to ensure NLM requests are working correctly.

* SUNRPC: Clean-up after previous patches.Chuck Lever2006-09-221-1/+0
| | | | | | | | | | Remove some unused macros related to accessing an RPC peer address Test plan: Compile kernel with CONFIG_NFS option enabled. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NLM: Fix reclaim racesTrond Myklebust2006-06-091-0/+1
| | | | | | | | | Currently it is possible for a task to remove its locks at the same time as the NLM recovery thread is trying to recover them. This quickly leads to an Oops. Protect the locks using an rw semaphore while they are being recovered. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* [PATCH] sem2mutex: fs/Ingo Molnar2006-03-261-9/+10
| | | | | | | | | | | | | | | | | | Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.

* lockd: Fix Oopses due to list manipulation errors.Trond Myklebust2006-03-201-2/+5
| | | | | | | | The patch "stop abusing file_lock_list introduces a couple of bugs since the locks may be copied and need to be removed from the lists when they are destroyed. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* lockd: stop abusing file_lock_listChristoph Hellwig2006-03-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently lockd directly access the file_lock_list from fs/locks.c. It does so to mark locks granted or reclaimable. This is very suboptimal, because a) lockd needs to poke into locks.c internals, and b) it needs to iterate over all locks in the system for marking locks granted or reclaimable. This patch adds lists for granted and reclaimable locks to the nlm_host structure instead, and adds locks to those. nlmclnt_lock: now adds the lock to h_granted instead of setting the NFS_LCK_GRANTED, still O(1) nlmclnt_mark_reclaim: goes away completely, replaced by a list_splice_init. Complexity reduced from O(locks in the system) to O(1) reclaimer: iterates over h_reclaim now, complexity reduced from O(locks in the system) to O(locks per nlm_host) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* lockd: Make lockd use rpc_new_client() instead of rpc_create_clientTrond Myklebust2006-03-201-1/+2
| | | | | | | | When doing NLM_GRANTED requests, lockd may end up blocking if we use rpc_create_client() due to the synchronous call to rpc_ping(). Instead, use rpc_new_client(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: new interface to force an RPC rebindChuck Lever2006-01-061-2/+2
| | | | | | | | | | | | | | | We'd like to hide fields in rpc_xprt and rpc_clnt from upper layer protocols. Start by creating an API to force RPC rebind, replacing logic that simply sets cl_port to zero. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked. Probably need to rig a server where certain services aren't running, or that returns an error for some typical operation.

* [PATCH] RPC: remove xprt->nocongChuck Lever2005-09-231-1/+0
| | | | | | | | | | | Get rid of the "xprt->nocong" variable. Test-plan: Use WAN simulation to cause sporadic bursty packet loss with UDP mounts. Look for significant regression in performance or client stability. Signed-off-by: Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* [PATCH] RPC: get rid of xprt->streamChuck Lever2005-09-231-2/+1
| | | | | | | | | | | | Now we can fix up the last few places that use the "xprt->stream" variable, and get rid of it from the rpc_xprt structure. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP.

* [PATCH] RPC: Make rpc_create_client() probe server for RPC program+version ↵Trond Myklebust2005-06-221-2/+2
| | | | | | | | | | | | 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. This enables us to immediately return an error to "mount" if it turns out that the server is only supporting NFSv2, when we requested NFSv3 or NFSv4.

* [PATCH] RPC: Make rpc_create_client() destroy the transport on failure.Trond Myklebust2005-06-221-3/+1

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+346
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!
