When we attempt to open a directory that\ndoes not have a cached dentry, that open now errors out with EISDIR. If\nyou attempt the same open with a cached dentry, it will succeed.\n\nFix this by reverting the change in nfs_atomic_lookup and allowing\nattempts to open directories to fall back to a normal lookup\n\nAlso, add a NFSv4-specific f_ops-\u003eopen routine that just returns\n-ENOTDIR. This should never be called if things are working properly,\nbut if it ever is, then the dprintk may help in debugging.\n\nTo facilitate this, a new file_operations field is also added to the\nnfs_rpc_ops struct.\n\nCc: stable@kernel.org\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "374e4e3ec347d4f70e1417ce3e1c454f133dab72", "tree": "9309b00af4c76c2f24854a15ce9e3d3f14741862", "parents": [ "0c0308066ca53fdf1423895f3a42838b67b3a5a8" ], "author": { "name": "Bryan Schumaker", "email": "bjschuma@netapp.com", "time": "Fri Jul 29 11:49:06 2011 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Jul 30 14:37:14 2011 -0400" }, "message": "Additional readdir cookie loop information\n\nPrint out the name of the file that triggers the cookie loop message to\nmake it slightly easier to track down the cause.\n\nSigned-off-by: Bryan Schumaker \u003cbjschuma@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "0c0308066ca53fdf1423895f3a42838b67b3a5a8", "tree": "4c6f0d852456581a7ca17286601d18d7bb030632", "parents": [ "ed1e6211a0a134ff23592c6f057af982ad5dab52" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Jul 30 12:45:35 2011 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Jul 30 14:34:50 2011 -0400" }, "message": "NFS: Fix spurious readdir cookie loop messages\n\nIf the directory contents change, then we have to accept that the\nfile-\u003ef_pos value may shrink if we do a \u0027search-by-cookie\u0027.

The only call site (xdr_decode() in fs/nfs/dir.c) simply\nextracts the errno value encoded in the pointer. Replace the\nreturned pointer with a standard integer errno return value.\n\nAlso, pass the \"server\" argument as part of the nfs_entry instead of\nas a separate parameter. It\u0027s faster to derive \"server\" in\nnfs_readdir_xdr_to_array() since we already have the directory\u0027s inode\nhandy. \"server\" ought to be invariant for a set of entries in the\nsame directory, right?\n\nThe legacy versions of decode_dirent() don\u0027t use \"server\" anyway, so\nit\u0027s wasted work for them to derive and pass \"server\" for each entry.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nTested-by: J.
