| |
Commit ba6fdda4 (profiling: Remove unused timer hook) removed [un]register_timer_hook due to a lack of upstream users and a belief that there were no out-of-tree users. However, systemtap uses it and with that patch applied, some stap scripts fail with
WARNING: "unregister_timer_hook" [/tmp/stapJoLMxD/stap_de6e19eaf7bd94629aba9d6f56cdfca5_8156.ko] undefined! WARNING: "register_timer_hook" [/tmp/stapJoLMxD/stap_de6e19eaf7bd94629aba9d6f56cdfca5_8156.ko] undefined!

Try again with another '--vp 00001' option. Unexpected exit of STAP script at ./watch-dstate.pl line 305.
Can the patch be reverted or at least put a warning in place about it being obsoleted until the systemtap folks come up with a replacement?
Systemtap folk, has his problem already been addressed?
