Rewrite the O_DIRECT code so that it can share the same coalescing\n and pNFS functionality as the page cache code.\n - Allow the server to provide hints as to when we should use pNFS,\n and when it is more efficient to read and write through the\n metadata server.\n - NFS cache consistency updates:\n * Use the ctime to emulate a change attribute for NFSv2/v3 so that\n all NFS versions can share the same cache management code.\n * New cache management code will only look at the change attribute\n and size attribute when deciding whether or not our cached data\n is still valid or not.\n * Don\u0027t request NFSv4 post-op attributes on writes in cases such as\n O_DIRECT, where we don\u0027t care about data cache consistency, or\n when we have a write delegation, and know that our cache is still\n consistent.\n * Don\u0027t request NFSv4 post-op attributes on operations such as\n COMMIT, where there are no expected metadata updates.\n * Don\u0027t request NFSv4 directory post-op attributes in cases where\n the operations themselves already return change attribute\n updates: i.e. operations such as OPEN, CREATE, REMOVE, LINK and\n RENAME.\n - Speed up \u0027ls\u0027 and friends by using READDIR rather than READDIRPLUS\n if we detect no attempts to lookup filenames.\n - Improve the code sharing between NFSv2/v3 and v4 mounts\n - NFSv4.1 state management efficiency improvements\n -

Currently, the rq_xtime field is\ninitialized by each transport just before it starts enqueing a request to\nbe sent. However, transports do not handle initializing this value\nconsistently; sometimes they don\u0027t initialize it at all.\n\nTo make the measurement of request round-trip time consistent for all\nRPC client transport capabilities, pull rq_xtime initialization into the\nRPC client\u0027s generic transport logic. Now all transports will get a\nstandardized RTT measure automatically, from:\n\n xprt_transmit()\n\nto\n\n xprt_complete_rqst()\n\nThis makes round-trip time calculation more accurate for the TCP transport.\nThe socket -\u003esendmsg() method can return \"-EAGAIN\" if the socket\u0027s output\nbuffer is full, so the TCP transport\u0027s -\u003esend_request() method may call\nthe -\u003esendmsg() method repeatedly until it gets all of the request\u0027s bytes\nqueued in the socket\u0027s buffer.\n\nCurrently, the TCP transport sets the rq_xtime field every time through\nthat loop so the final value is the timestamp just before the *last* call\nto the underlying socket\u0027s -\u003esendmsg() method. After this patch, the\nrq_xtime field contains a timestamp that reflects the time just before the\n*first* call to -\u003esendmsg().\n\nThis is consequential under heavy workloads because large requests often\ntake multiple -\u003esendmsg() calls to get all the bytes of a request queued.\nThe TCP transport causes the request to sleep until the remote end of the\nsocket has received enough bytes to clear space in the socket\u0027s local\noutput buffer. This delay can be quite significant.\n\nThe method introduced by this patch is a more accurate measure of RTT\nfor stream transports, since the server can cause enough back pressure\nto delay (ie increase the latency of) requests from the client.\n\nAdditionally, this patch corrects the behavior of the RDMA transport, which\nentirely neglected to initialize the rq_xtime field. RPC performance\nmetrics for RDMA transports now display correct RPC request round trip\ntimes.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nAcked-by: Tom Talpey \u003cthomas.talpey@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "cd983ef81b9d79573848dabf81277c7314220257", "tree": "954f22ca07ff077e50b05ef54c87491cd8506bce", "parents": [ "48186c7d5734a6b137f9186b37f6dc98097d0429" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Wed Jun 11 17:56:13 2008 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jul 09 12:09:06 2008 -0400" }, "message": "SUNRPC: Remove obsolete messages during transport connect\n\nRecent changes to the RPC client\u0027s transport connect logic make connect\nstatus values ECONNREFUSED and ECONNRESET impossible.\n\nClean up xprt_connect_status() to account for these changes.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "77a50df2b14c8d3ee3c58c21c4a0e0157570df09", "tree": "0e324a712e5e768c8353b0b5ba6ddc31095479f0", "parents": [ "96fffeb4b413a4f8f65bb627d59b7dfc97ea0b39", "358c12953b88c5a06a57c33eb27c753b2e7934d1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 09:44:11 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 09:44:11 2008 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:\n iwlwifi: Allow building iwl3945 without iwl4965.\n wireless: Fix compile error with wifi \u0026 leds\n tcp: Fix slab corruption with ipv6 and tcp6fuzz\n ipv4/ipv6 compat: Fix SSM applications on 64bit kernels.\n [IPSEC]: Use digest_null directly for auth\n sunrpc: fix missing kernel-doc\n can: Fix copy_from_user() results interpretation\n Revert \"ipv6: Fix typo in net/ipv6/Kconfig\"\n tipc: endianness annotations\n ipv6: result of csum_fold() is already 16bit, no need to cast\n [XFRM] AUDIT: Fix flowlabel text format ambibuity.\n" }, { "commit": "0b80ae4201e5128e16e5161825f5cd377a5d1fee", "tree": "1d0d74621550e3a4f595946bb85896a6ea15a065", "parents": [ "3f91bd420a955803421f2db17b2e04aacfbb2bb8" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Sat Apr 26 22:59:02 2008 -0700" }, "committer": { "name": "David S.

deadlock...\n\nBrian Behlendorf writes:\n\nThe root cause of the NFS hang we were observing appears to be a rare\ndeadlock between the kernel provided usermodehelper API and the linux NFS\nclient. The deadlock can arise because both of these services use the\ngeneric linux work queues. The usermodehelper API run the specified user\napplication in the context of the work queue. And NFS submits both cleanup\nand reconnect work to the generic work queue for handling. Normally this\nis fine but a deadlock can result in the following situation.\n\n - NFS client is in a disconnected state\n - [events/0] runs a usermodehelper app with an NFS dependent operation,\n this triggers an NFS reconnect.\n - NFS reconnect happens to be submitted to [events/0] work queue.\n - Deadlock, the [events/0] work queue will never process the\n reconnect because it is blocked on the previous NFS dependent\n operation which will not complete.`\n\nThe solution is simply to run reconnect requests on rpciod.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "a509050bd3b8e0aa269c2241aa10d74ca7701e2f", "tree": "47860feb054c6c286fd10c7d19a5ed3c3efb5c32", "parents": [ "c5a4dd8b7c15927a8fbff83171b57cad675a79b9" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Thu Mar 29 16:48:04 2007 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Apr 30 22:17:12 2007 -0700" }, "message": "SUNRPC: introduce rpcbind: replacement for in-kernel portmapper\n\nIntroduce a replacement for the in-kernel portmapper client that supports\nall 3 versions of the rpcbind protocol.
