Ocfs2 devel - Jun 2012 - fix mlog_errno in ocfs2_global_read_info

Hi, All,

When mount ocfs2 with option usrquota and grpquota, we will see below 
message:

(mount.ocfs2,9434,1):ocfs2_global_read_info:403 ERROR: status = 24
(mount.ocfs2,9434,3):ocfs2_global_read_info:403 ERROR: status = 24

But actually this should not be a error.

In ocfs2_global_read_info, if  read_quota() succeed, status is the size 
of the struct ocfs2_global_disk_dqinfo, only when it is not equal to the 
correct size, it will be a error. So this positive value should be 
return and should not log it as a error.

I made a patch to fix this, and in the patch I removed the redundant 
mlog_errno also.

Thanks for review

Tiger

out_err already logged all the negative status, so remove mlog_errno
before goto there. If quota_read succeed, positive (non zero)
status should be return and it's not a error.

Don`t use usrquota and grpquota - this is amazing unstable i wait for patch 
7 month and still in progress....
And FYI this is not only this error look i got many many in dmesg when 
someone get email and he is over quota there is error in dmesg like this:
(local,29785,2):ocfs2_write_begin:1953 ERROR: status = -122
(courier-imapd,26241,1):ocfs2_write_begin:1953 ERROR: status = -122

And many many other errors with status -122... if possible disable quota or 
You get kernel panic when u write/read/move file with FS quota support on 
ocfs2 cluster.
Thanks
