NFS: missing nfs_fattr_init in nfs3_proc_getacl and nfs3_proc_setacls (resend #2)
Jeff Layton [Mon, 18 Aug 2008 13:17:58 +0000 (09:17 -0400)]
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...
