I have enabled debugging and tracing features in XFS
using the 2.4.26 kernel.  When I load the xfs module,
it reports that tracing and debugging are enabled.

(From dmesg)
SGI XFS with tracing, debug enabled
SGI XFS Quota Management subsystem

To enable tracing, the Configure.help file says to set
/proc/sys/vm/pagebuf/debug.  However, I could not find this
sysctl, or anything that was similar in the /proc/fs/xfs or
/proc/sys/fs/xfs directories.

How do I turn this on?

Also, with debugging enabled, do all debug messages go to the
kernel log?

Thanks,
Craig
