This commit adds a new Uprobe option: RefCtrOffset. This option will let the kernel manage automatically SDT notes reference counts (semaphores). Both the tracefs API and the perf API supports it, but it is available starting from kernel version 4.20+. Signed-off-by: Mattia Meleleo <melmat@tuta.io>
This commit refactors [k,u]probe arguments into a struct improving the readability of function signatures. Signed-off-by: Mattia Meleleo <melmat@tuta.io>
