Bug ID: 15663
Summary: Failing to remove the stap kernel modules on kernel
3.9.4
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: agentzh at gmail dot com
On Linux kernel 3.9.4 x86_64, we're always seeing that stap fails to remove the
kernel module upon exit:
# stap -e 'probe begin { print("Hello\n") exit() }'
Hello
Error removing module 'stap_72392efe884b8779ed83364cfbcd97e0_965': Device or
resource busy.
WARNING: /usr/local/systemtap/bin/staprun exited with status: 1
Pass 5: run failed. [man error::pass5]
And we can see the kernel modules are still there:
# lsmod | grep stap
stap_db98a89434ce6c6d11c1e43dd3b758df_11003 242671 0 [permanent]
stap_41ed56b577691483d1b190b51ee07fe1_12277 241903 0 [permanent]
The systemtap version that we're using:
# stap --version
Systemtap translator/driver (version 2.2/0.155, non-git sources)

enabled features: BOOST_SHARED_PTR TR1_UNORDERED_MAP NLS
And CONFIG_MODULE_UNLOAD is enabled in our kernel:
# grep CONFIG_MODULE_UNLOAD /boot/config-`uname -r`
CONFIG_MODULE_UNLOAD=y
Any help will be highly appreciated.
Thanks!
