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.

Once XPT_DEAD is set,\n(And XPT_BUSY is clear) that initial reference is dropped and the xprt\ncan be freed.\n\nSo when a creator clears XPT_BUSY it is dropping its only reference and\nso must not touch the xprt again.\n\nHowever svc_recv, after calling -\u003expo_accept (and so getting an XPT_BUSY\nreference on a new xprt), calls svc_xprt_recieved. This clears\nXPT_BUSY and then svc_xprt_enqueue - this last without owning a reference.\nThis is dangerous and has been seen to leave svc_xprt_enqueue working\nwith an xprt containing garbage.\n\nSo we need to hold an extra counted reference over that call to\nsvc_xprt_received.\n\nFor safety, any time we clear XPT_BUSY and then use the xprt again, we\nfirst get a reference, and the put it again afterwards.\n\nNote that svc_close_all does not need this extra protection as there are\nno threads running, and the final free can only be called asynchronously\nfrom such a thread.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nCc: stable@kernel.org\nSigned-off-by: J.

However, xs_bind() subsequently uses\nthe value of this field without regard to whether the source address\nwas initialized during transport creation or not.\n\nSo far we\u0027ve been lucky: the uninitialized value of this field is\nzeroes. xs_bind(), until recently, used only the sin[6]_addr field in\nthis sockaddr, and all zeroes is a valid value for this: it means\nANYADDR. This is a happy coincidence.\n\nHowever, xs_bind() now wants to use the sa_family field as well, and\nexpects it to be initialized to something other than zero.\n\nTherefore, the source address sockaddr field should be fully\ninitialized at transport create time in _every_ case, not just when\nthe RPC application wants to use a specific bind address.\n\nBruce added a workaround for this missing initialization by adjusting\ncommit 6bc9638a, but the \"right\" way to do this is to ensure that the\nsource address sockaddr is always correctly initialized from the\nget-go.\n\nThis patch doesn\u0027t introduce a behavior change. It\u0027s simply a\nclean-up of Bruce\u0027s fix, to prevent future problems of this kind. It\nmay look like overkill, but\n\n a) it clearly documents the default initial value of this field,\n\n b) it doesn\u0027t assume that the sockaddr_storage memory is first\n initialized to any particular value, and\n\n c) it will fail verbosely if some unknown address family is passed\n in\n\nOriginally introduced by commit d3bc9a1d.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: J.
