Subject:    [PATCH] NFS: missing nfs_fattr_init in nfs3_proc_getacl and nfs3_proc_setacls (resend)

[Download RAW message or body]

The fattrs used in the NFSv3 getacl/setacl calls are not being properly
initialized. This occasionally causes nfs_update_inode to fall into
NFSv4 specific codepaths when handling post-op attrs from these calls.

Thanks to Cai Qian for noticing the spurious NFSv4 messages in debug
output from a v3 mount...
