Re: Latest systemtap fails when used with latest Linux kernel

[Srikar Dronamraju <srikar@linux.vnet.ibm.com>]

Hi Ted, 

This error is occuring because of uid,gid,  fields in task_struct being
moved over to struct cred patch. Kamalesh has already raised a bug
http://sourceware.org/bugzilla/show_bug.cgi?id=9699 for the same.

Thanks and Regards
