Hi
In user-space probing, the uprobe module will be
resident in memory even the stap exists.
[wjhuang@F10-32bits systemtap]$ /sbin/lsmod|grep uprobe
[wjhuang@F10-32bits systemtap]$ sudo stap -e 'probe
process("/home/wjhuang/Download/git-1.5.6/git").function("main"){}'
WARNING: side-effect-free probe 'probe_1383': keyword at <input>:1:1
source: probe
process("/home/wjhuang/Download/git-1.5.6/git").function("main"){}
^
^C[wjhuang@F10-32bits systemtap]/sbin/lsmod|grep uprobe
uprobes 24176 0
Is this on purpose or some specific consideration?
Regards,
Wenji
