Modified files:
sys/kern kern_ktrace.c
Log:
- Change utrace ktrace events to malloc the work buffer before getting a
request structure.
- Re-optimize the case of utrace being disabled by doing an explicit
KTRPOINT check instead of relying on the one in ktr_getrequest() so that
we don't waste time on a malloc in the non-tracing case.
- Change utrace() to return an error if the copyin() fails. Before it
would just ignore the request but still return success. This last is
a change in behavior and can be backed out if necessary.
