ChenXiaoSong 6f52d4cda0 NFSv4: fix open failure with O_ACCMODE flag ... [ Upstream commit b243874f6f ] open() with O_ACCMODE|O_DIRECT flags secondly will fail. Reproducer: 1. mount -t nfs -o vers=4.2 $server_ip:/ /mnt/ 2. fd = open("/mnt/file", O_ACCMODE|O_DIRECT|O_CREAT) 3. close(fd) 4. fd = open("/mnt/file", O_ACCMODE|O_DIRECT) Server nfsd4_decode_share_access() will fail with error nfserr_bad_xdr when client use incorrect share access mode of 0. Fix this by using NFS4_SHARE_ACCESS_BOTH share access mode in client, just like firstly opening.
