These FRMR are used\nacross connections on the same mount, i.e. if the connection goes\naway on an idle timeout and reconnects later, the FRMR are not\ndestroyed and recreated.\n\nThis creates a problem for transport errors because the WR that\ninvalidate an FRMR may be flushed (i.e. fail) leaving the\nFRMR valid. When the FRMR is later used to map an RPC it will fail,\ntearing down the transport and starting over. Over time, more and\nmore of the FRMR pool end up in the wrong state resulting in\nseemingly random disconnects.\n\nThis fix keeps track of the FRMR state explicitly by setting it\u0027s\nstate based on the successful completion of a reg/inv WR.

This means that when we\nexit, we want all references to the rpc_task to be gone, and we want\nany dentry references etc. held by that task to be released.\n\nFor this reason these functions call __rpc_wait_for_completion_task(),\nfollowed by rpc_put_task() in the expectation that the latter will be\nreleasing the last reference to the rpc_task, and thus ensuring that the\ncallback_ops-\u003erpc_release() has been called synchronously.\n\nThis patch fixes a race which exists due to the fact that\nrpciod calls rpc_complete_task() (in order to wake up the callers of\n__rpc_wait_for_completion_task()) and then subsequently calls\nrpc_put_task() without ensuring that these two steps are done atomically.\n\nIn order to avoid adding new spin locks, the patch uses the existing\nwaitqueue spin lock to order the rpc_task reference count releases between\nthe waiting process and rpciod.\nThe common case where nobody is waiting for completion is optimised for by\nchecking if the RPC_TASK_ASYNC flag is cleared and/or if the rpc_task\nreference count is 1: in those cases we drop trying to grab the spin lock,\nand immediately free up the rpc_task.\n\nThose few processes that need to put the rpc_task from inside an\nasynchronous context and that do not care about ordering are given a new\nhelper: rpc_put_task_async().\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "352b5d13c0684ba8cd103aa20cb74f105334562a", "tree": "a54ffeec78ed69035c4c99faa61e472230d14076", "parents": [ "0997b173609b9229ece28941c118a2a9b278796e" ], "author": { "name": "J.

"fs: icache RCU free inodes\n\nRCU free the struct inode. This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations.
