Hi,
I am at the point where I need to fix the "-z" option of
nfsstat. Currently the stats are acquired/zeroed for the
old NFS subsystem via sysctl. The setup in the kernel is:
SYSCTL_STRUCT(_vfs_nfs, NFS_NFSSTATS, nfsstats, CTLFLAG_RW,
&nfsstats, nfsstats, "S,nfsstats");
The new NFS subsystem currently gets the contents of the
structure via a flag on nfssvc(2).
So, I could either:
- add another flag for nfssvc(2) to zero the structure
OR
- switch the new NFS subsystem over to using a SYSCTL_STRUCT()
like the above.
Which do you think would be preferable?
Thanks in advance for any info, rick
ps: I got completely lost on the SYSCTL thread in Jan. and
would rather not start another one like it:-)
