Hi, Here is the 2nd version of the series to register fprobe only when the fprobe event is enabled. The previous version is here;
https://lore.kernel.org/all/174212767109.348872.18231451508464729427.stgit@devnote2/ In this version, I added fixes([1/7] and [2/7]) related to module unloading ([1/7] should be handled separatedly) and updates according to the previous thread. Steve suggested the fprobe-events are always registered when it is defined, even if it is disabled and that makes system overhead. This series registeres the fprobes only when the event is enabled.
