Hi all,
I am wondering whether it is possible to call a userspace routine from within the kernel, say a module or something. The Linux Kernel Hacker Guide states as one solution to call kerneld from kernel mode and have it execute a seperate program. Since kerneld had been replaced with kmod, and the kmod documentation states it can only be used to load modules on demand this solution clearly is not an option anymore.
Unfortunately this leaves my question unanswered, and that's why I am turning to you, dear kernel list reader :). As I am not subscribed to the list could anyone who is willing to answer please also CC his/her remarks to my email address? I will of course also regularly check the mailinglist archive.
( Little background info: I am thinking about an extension to the kernel via a kernel module. Userspace processes can register themselves with that module and be called whenever some condition in the kernel is met. When someone has another idea about how to handle this situation I would certainly like to hear it. )
Thanks in advance,
Arjan Opmeer
