  "message": "NFS: Set meaningful value for fattr-\u003etime_start in readdirplus results.\n\nDon\u0027t use uninitialsed value for fattr-\u003etime_start in readdirplus results.\n\nThe \u0027fattr\u0027 structure filled in by nfs3_decode_direct does not get a\nvalue for -\u003etime_start set.\nThus if an entry is for an inode that we already have in cache,\nwhen nfs_readdir_lookup calls nfs_fhget, it will call nfs_refresh_inode\nand may update the inode with out-of-date information.\n\nDirectories are read a page at a time, so each page could have a\ndifferent timestamp that \"should\" be used to set the time_start for\nthe fattr for info in that page.  However storing the timestamp per\npage is awkward.  (We could stick in the first 4 bytes and only read 4092\nbytes, but that is a bigger code change than I am interested it).\n\nThis patch ignores the readdir_plus attributes if a readdir finds the\ninformation already in cache, and otherwise sets -\u003etime_start to the time\nthe readdir request was sent to the server.\n\nIt might be nice to store - in the directory inode - the time stamp for\nthe earliest readdir request that is still in the page cache, so that we\ndon\u0027t ignore attribute data that we don\u0027t have to.  This patch doesn\u0027t do\nthat.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n",
