transports\n\nTI-RPC introduces the capability of performing RPC over AF_LOCAL\nsockets.

Kernel ULPs must specify the pathname of the remote endpoint\nwhen an AF_LOCAL transport is created. rpcbind supports registering\nservices available via AF_LOCAL, so the kernel could handle it with\nsome adjustment to -\u003erpcbind and -\u003eset_port. But we don\u0027t need this\nfeature for doing upcalls via well-known named sockets.\n\nThis has not been tested with ULPs that move a substantial amount of\ndata.

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.
