| H A D | nfs4file.c | b243874f Tue Mar 29 06:32:08 CDT 2022 ChenXiaoSong <chenxiaosong2@huawei.com> NFSv4: fix open failure with O_ACCMODE flag
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.
