i wrote a patch that got rejected because it did not apply cleanly to the tree of greg kh https://lkml.org/lkml/2021/8/18/304
the file i modified is drivers/staging/rtl8723bs/include/rtl8192c_recv.h
get_maintainer.pl gave me the list of emails to send the patch to, and i used it for that purpose. the file Documentation/process/submitting-patches.rst says to see the T: entry for the subsystem in MAINTAINERS to find the right tree to base the patch on. i tried searching through MAINTAINERS and found that there are a few subsystems that start with RTL8*.
greg kh is listed a few times in MAINTAINERS, so i'm not able to find the exact tree to start with by looking for the maintainer.
is there a systematic way of finding the subsystem, given a file?
Yes, use the tool you already used: $ ./scripts/get_maintainer.pl drivers/staging/rtl8723bs/include/rtl8192c_recv.h Greg Kroah-Hartman <gregkh@linuxfoundation.org> (supporter:STAGING SUBSYSTEM) linux-staging@lists.linux.dev (open list:STAGING SUBSYSTEM) linux-kernel@vger.kernel.org (open list) That shows this file is in the staging subsystem, and there's the list to send the patch to, as well as the person you should cc: on it.
in addition, how do i know what branch to use? the T: entries have a repo, but not a branch name.
You can always ask the subsystem maintainer about what branch to use if you have a question. thanks, greg k-h
