Oh wait, actually looking at this again I think don't understand just yet. This is pretty common and when you apply the series git am will cut after the first --- And thinking about it so far I've never heard anyone complain about this. But likely I just misunderstand you and I really borked something. Fwiw, this format seems documented at https://www.kernel.org/doc/html/latest/process/submitting-patches.html "The --- marker line serves the essential purpose of marking for patch handling tools where the changelog message ends. One good use for the additional comments after the --- marker is for a diffstat, to show what files have changed, and the number of inserted and deleted lines per file. A diffstat is especially useful on bigger patches. Other comments relevant only to the moment or the maintainer, not suitable for the permanent changelog, should also go here. A good example of such comments might be patch changelogs which describe what has changed between the v1 and v2 version of the patch. If you are going to include a diffstat after the --- marker, please use diffstat options -p 1 -w 70 so that filenames are listed from the top of the kernel source tree and don’t use too much horizontal space (easily fit in 80 columns, maybe with some indentation). (git generates appropriate diffstats by default.)" And also at https://www.ozlabs.org/~akpm/stuff/tpp.txt "g) Non-changelog text: Sometimes you want to include text in the email which isn't designed to go into the changelog in the git repository. Things like "this is already in Fred's tree" or "this is an updated version of last Friday's patch" or whatever. You should place such text below the "^---" separator so that it is auto-removed when being placed into the revision control system." And there are quite a few examples that do it this way just one random pick from my inbox: https://lore.kernel.org/lkml/20210316204252.427806-8-mic@digikod.net Christian ^ permalink raw reply [flat|nested] 22+ messages in thread

Oh now I understand you. That's intentional, non-final branches, i.e. versioned branches of mine or branches where I'm not the one applying the patches after pulling them via b4 still container the changelogs because I need to assume I'll cut new version from it and will amend the changelogs. This also ensures git format-patch will give retain the changelog. But the point is will taken. If I provide a branch to pull from I should strip the changelogs. This is what I done now. You can find this series (unchanged apart from the stripped changelog) here: always have the changelog recorded to https://github.com/brauner/xfstests/ idmapped_mounts similar for gitlab and kernel.org.

Wong, David Howells, Christian Brauner From: Christian Brauner <christian.brauner@ubuntu.com> This is basically a re-implementation of xfs/050 but each file creation call is done through an idmapped mount which verifies that the semantics are identical even when the mount is idmapped.

Ok, Konstantin confirmed that patch 2/6 got dropped because of it's size. Nothing to do about this now but just as an fyi. Thanks! Christian ^ permalink raw reply [flat|nested] 22+ messages in thread

I would personally not bother with obscure tags like 'unlink' but whatever. Two things I would request are: 1. Keep 'auto quick' before all other tags. There is no strong rule about this format, but that's the common practice and it makes sense IMO because -g auto and -g quick are the far more commonly used groups of tests, so it's convenient to be able to 'eye grep' those tests in the group file. 2. Please tags all the idmapped tests with a tag 'idmapped' (or whatever) This would be used for running tests with -g idmapped for quick sanity when modifiying idmapped mounts related code Thanks, Amir. ^ permalink raw reply [flat|nested] 22+ messages in thread

Though it's very unlikely for the kernel to assign a pid that is at least 100 billion. Even newest systems only bump the maximum pid number to 4m and we would've thankfully caught this in the snprintf()s below. > > if (geteuid() != 0 && map_type == ID_TYPE_GID) { > @@ -273,7 +273,7 @@ static int get_userns_fd_from_idmap(struct list *idmap) > { > int ret; > pid_t pid; > - char path_ns[STRLITERALLEN("/proc") + INTTYPE_TO_STRLEN(pid_t) + > + char path_ns[STRLITERALLEN("/proc/") + INTTYPE_TO_STRLEN(pid_t) + > STRLITERALLEN("/ns/user") + 1]; > > pid = do_clone(get_userns_fd_cb, NULL, CLONE_NEWUSER | CLONE_NEWNS); > @@ -364,7 +364,7 @@ int main(int argc, char *argv[]) > while ((ret = getopt_long_only(argc, argv, "", longopts, > &index)) != -1) { > switch (ret) { > case 'a': > - if (strnequal(optarg, "/proc", > STRLITERALLEN("/proc/"))) { > + if (strnequal(optarg, "/proc/", > STRLITERALLEN("/proc/"))) { > fd_userns = open(optarg, O_RDONLY | O_CLOEXEC); That's currently not used by the code and would've simply meant we failed. Will fix this up and push it to the tree I linked to earlier. Thank you! Christian ^ permalink raw reply [flat|nested] 22+ messages in thread

You are right. It should be fine as is. I may have messed up something else while building. You may take the fix or leave it - as you wish.

Eh, it kinda makes it more obvious to have the lines there and they don't hurt so I've added your change. Christian ^ permalink raw reply [flat|nested] 22+ messages in thread
