* Fix hrtimer.expires name change.Josh Stone2008-10-242-0/+10
| | | | | | The field is renamed to _expires starting in 2.6.28-rc1, and it's not meant to be directly manipulated. Instead hrtimer users are supposed to use hrtimer_get_expires and hrtimer_set_expires.

* PR4886: check build-id if able.Wenji Huang2008-10-065-1/+101
| | | | This provides sanity check of debuginfo file based on build-id. Many cases are considered, whether build-id exists in debuginfo file or not, whether module is loaded or not, whether build-id exists in runtime kernel/module. It will do work when LD >= 2.18 and kernel >=2.6.23, otherwise no check.
