With the current API design you'd able to easily confine the "pre" code
inside the "set" function, and the "post" code inside the "unset"
function. It looks pretty clean to me, and allows to limit the knowledge
of sys_indirect, the more as possible inside kernel/indirect.c.
But this will not be applicable. We already discussed that each
syscall likely needs its own set of flags etc. There really isn't
much overlap if any which cannot be handled at least as well using a
flat structure. You're adding major complications for something which
IMO will never be usable. With the flat structure to whole overhead
of sys_indirect is limited to a test for valid syscalls, copying the
struct, making the call to the syscall function, and resetting the
value in current. Very simple and fast.
