docs: fix references to docs/devel/tracing.rst Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

trace-events: Shorten file names in comments We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.

# signal.c
linux-user: fix use of SIGRTMIN Some RT signals can be in use by glibc, it's why SIGRTMIN (34) is generally greater than __SIGRTMIN (32). So SIGRTMIN cannot be mapped to TARGET_SIGRTMIN. Instead of swapping only SIGRTMIN and SIGRTMAX, map all the range [TARGET_SIGRTMIN ... TARGET_SIGRTMAX - X] to [__SIGRTMIN + X ... SIGRTMAX ] (SIGRTMIN is __SIGRTMIN + X).

trace-events: Fix attribution of trace points to source Some trace points are attributed to the wrong source file. Happens when we neglect to update trace-events for code motion, or add events in the wrong place, or misspell the file name. Clean up with help of cleanup-trace-events.pl. Same funnies as in the previous commit, of course. Manually shorten its change to linux-user/trace-events to */signal.c.
