Description of problem:
statfs on NFS partition always returns 0 regardless of success/fail.
Steps to Reproduce:
1. Start NFS service:
# echo "/test *(rw,no_root_squash)" >> /etc/exports
# service nfs start
2. Setup client:
# mount -t nfs -o soft,timeo=5 server:/test /mnt/nfs
3. Stop NFS service:
# service nfs stop
4. From the client, run the attached test program:
Actual results:
The program returns with 0, which actually should return negative number according to statfs(2) but returns 0.
Expected results:
Should return negative number.
According to the call trace nfs_statfs is not returning the value properly.
sys_statfs() => return 0
vfs_statfs() => return 0
nfs_statfs() => return 0
nfs3_proc_statfs() => return -5
