When IO is done if all\nwas well the io_state is freed. (as today). If the I/O has ended with an\nerror, the io_state is queued on a per-layout err_list. When eventually\nencode_layoutreturn() is called, each error is properly encoded on the\nXDR buffer and only then the io_state is removed from err_list and\nde-allocated.\n\nIt is up to the io_engine to fill in the segment that fault and the type\nof osd_error that occurred. By calling objlayout_io_set_result() for\neach failing device.\n\nIn objio_osd:\n* Allocate io-error descriptors space as part of io_state\n* Use generic objlayout error reporting at end of io.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "04a555498e03b3804e2dec916a4669f5f560e503", "tree": "4fab39683df70cee7f7aea7d7718072a811ad153", "parents": [ "8a1636c459cb7a4b32ba4024cd1b2ba21fba6aed" ], "author": { "name": "Andy Adamson", "email": "andros@netapp.com", "time": "Sun May 22 19:53:10 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:37 2011 +0300" }, "message": "pnfs: encode_layoutreturn\n\nAdd a layout driver method to encode the layout type specific\nopaque part of layout return in-line in the xdr stream.\n\nCurrently the pnfs-objects layout driver uses it to encode i/o error\ninformation on LAYOUTRETURN.\n\nSigned-off-by: Andy Adamson \u003candros@netapp.com\u003e\n[fixup layout header pointer for encode_layoutreturn]\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "8a1636c459cb7a4b32ba4024cd1b2ba21fba6aed", "tree": "f9c46f272b98ceb65f997f226d47da68c6fcac6b", "parents": [ "cbe8260369c9f88eafa035cd327dc3e02fad528c" ], "author": { "name": "Benny Halevy", "email": "bhalevy@panasas.com", "time": "Wed Jul 14 15:43:57 2010 -0400" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:36 2011 +0300" }, "message": "pnfs: layoutret_on_setattr\n\nWith the objects layout security model, we have object capabilities\nthat are associated with the layout and we anticipate that the server\nwill issue a cb_layoutrecall for any setattr that changes security\nrelated attributes (user/group/mode/acl) or truncates the file.\n\nTherefore, the layout is returned before issuing the setattr to avoid\nthe anticipated cb_layoutrecall.\n\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "cbe8260369c9f88eafa035cd327dc3e02fad528c", "tree": "13316d9b1a761cf58c35e663375b72f6ac07c5d2", "parents": [ "04f83450388e87d86b387cf4a27b81eb7e69de7d" ], "author": { "name": "Benny Halevy", "email": "bhalevy@panasas.com", "time": "Sun May 22 19:52:37 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:36 2011 +0300" }, "message": "pnfs: layoutreturn\n\nNFSv4.1 LAYOUTRETURN implementation\n\nCurrently, does not support layout-type payload encoding.\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\nSigned-off-by: Andy Adamson \u003candros@citi.umich.edu\u003e\nSigned-off-by: Andy Adamson \u003candros@netapp.com\u003e\nSigned-off-by: Dean Hildebrand \u003cdhildeb@us.ibm.com\u003e\nSigned-off-by: Fred Isaman \u003ciisaman@citi.umich.edu\u003e\nSigned-off-by: Fred Isaman \u003ciisaman@netapp.com\u003e\nSigned-off-by: Marc Eshel \u003ceshel@almaden.ibm.com\u003e\nSigned-off-by: Zhang Jingwang \u003czhangjingwang@nrchpc.ac.cn\u003e\n[call pnfs_return_layout right before pnfs_destroy_layout]\n[remove assert_spin_locked from pnfs_clear_lseg_list]\n[remove wait parameter from the layoutreturn path.]\n[remove return_type field from nfs4_layoutreturn_args]\n[remove range from nfs4_layoutreturn_args]\n[no need to send layoutcommit from _pnfs_return_layout]\n[don\u0027t wait on sync layoutreturn]\n[fix layout stateid in layoutreturn args]\n[fixed NULL deref in _pnfs_return_layout]\n[removed recaim member of nfs4_layoutreturn_args]\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "04f83450388e87d86b387cf4a27b81eb7e69de7d", "tree": "99c10d6a995ed1e7b872abb0127fc38d6bef9982", "parents": [ "d20581aa4be11407c9eeeb75992df5ef176bba0f" ], "author": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 22 19:52:19 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:15 2011 +0300" }, "message": "pnfs-obj: osd raid engine read/write implementation\n\nWith the use of the in-kernel osd library.

This could be a local packet\nfiltering issue on the client, but we didn\u0027t troubleshoot this\nfurther because of the reported \"git bisect\" result.\n\nLast fall we removed the ad hoc mount option parser in\nfs/nfs/nfsroot.c in favor of using the main parser in fs/nfs/super.c\n(see commit 56463e50 \"NFS: Use super.c for NFSROOT mount option\nparsing\"). That commit changed the default NFSROOT mount options to\nbe the same as those employed by user space mounts.\n\nAs it turns out, these new default mount options are not tolerated by\nmany embedded systems. So far these problems have been due to\nspecific behavior of certain embedded NICs. The NFS community does\nnot have such hardware on hand for running tests.\n\nCommit 53d47375 recently introduced a clean way to specify default\nmount options for NFSROOT, so we can now easily restore the\ntraditional defaults for NFSROOT:\n\n vers\u003d2,udp,rsize\u003d4096,wsize\u003d4096\n\nThis should revert the new default NFSROOT mount options introduced\nwith commit 56463e50.\n\nTested-by: Marek Belisto \u003cmarek.belisto@open-nandra.com\u003e\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "26f04dde681c6a48b2bacfc5fe01fef204419b0c", "tree": "b8a6f047b6e5743ab795076e3cc0d0a5a72840e6", "parents": [ "4b8ee2b82e8b0b6e17ee33feb74fcdb5c6d8dbdd" ], "author": { "name": "Lai Jiangshan", "email": "laijs@cn.fujitsu.com", "time": "Sun May 01 06:21:54 2011 -0700" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri May 27 17:42:46 2011 -0400" }, "message": "nfs,rcu: convert call_rcu(nfs_free_delegation_callback) to kfree_rcu()\n\nThe rcu callback nfs_free_delegation_callback() just calls a kfree(),\nso we use kfree_rcu() instead of the call_rcu(nfs_free_delegation_callback).\n\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nSigned-off-by: Paul E.
