Description

The lttng-ust(3) man page should be clarified regarding the scenarios where the liblttng-ust-fork.so wrapper is needed.

It should document that it is needed in scenarios where applications using fork(2), clone(2) (with CLONE_VM flag cleared), BSD's rfork(2), daemon(3), without immediately following those by an exec(3) family call. This includes scenarios where close(2) is used to close file descriptors before invoking exec(3), even though close(2) is listed as an async-signal-safe function.
