  "message": "gdb, gdbserver: split iterate_over_lwps into for_each_lwp and find_lwp\n\nEven though it works, I have always been mildly annoyed by\niterate_over_lwps being used for both iterating over all lwps and\nfinding one lwp matching a criterion.  I think it would be clearer to\nhave two functions for the two use cases.  Then it would be 100% clear\nat the call site what the intention is.  It would be clear that a\ncallback returning bool is meant to be a predicate for the find\nfunction, while a callback returning void is meant to be a callback for\nthe \"for each\" function.\n\nTherefore, split iterate_over_lwps in two:\n\n - find_lwp to find the first lwp matching a boolean predicate (and the\n   given ptid filter)\n - for_each_lwp to apply a function on all lwps (optionally filtering by\n   ptid or pid)\n\nThe callbacks given to for_each_lwp can now return void.\n\nIntroduce some overloads for for_each_lwp, for the various common use\ncases:\n\n - filtering by ptid\n - filtering by pid\n - no ptid/pid filter\n\nfind_lwp and two overloads of for_each_lwp are actually only used in\ngdb/linux-nat.c, so make them local to that file.  Only the pid variant\nof for_each_lwp is used in shared code.\n\nThe pattern used in this patch serves as the basis for subsequent\npatches that split other \"iterate over\" functions the same way.\n\nChange-Id: I49d3af0916622300cc81e3c32d22e1aff13cf38f\nApproved-By: Andrew Burgess \u003caburgess@redhat.com\u003e\n",
