   4 Descriptions of section entries and preferred order
   5 ---------------------------------------------------
   6
   7         M: *Mail* patches to: FullName <address@domain>
   8         R: Designated *Reviewer*: FullName <address@domain>
   9            These reviewers should be CCed on patches.
  10         L: *Mailing list* that is relevant to this area
  11         S: *Status*, one of the following:
  12            Supported:   Someone is actually paid to look after this.
  13            Maintained:  Someone actually looks after it.
  14            Odd Fixes:   It has a maintainer but they don't have time to do
  15                         much other than throw the odd patch in. See below..
  16            Orphan:      No current maintainer [but maybe you could take the
  17                         role as you write your new code].
  18            Obsolete:    Old code. Something tagged obsolete generally means
  19                         it has been replaced by a better system and you
  20                         should be using that.
  21         W: *Web-page* with status/info
  22         Q: *Patchwork* web based patch tracking system site
  23         B: URI for where to file *bugs*. A web-page with detailed bug
  24            filing info, a direct bug tracker link, or a mailto: URI.
  25         C: URI for *chat* protocol, server and channel where developers
  26            usually hang out, for example irc://server/channel.
  27         P: Subsystem Profile document for more details submitting
  28            patches to the given subsystem. This is either an in-tree file,
  29            or a URI. See Documentation/maintainer/maintainer-entry-profile.rst
  30            for details.
  31         T: *SCM* tree type and location.
  32            Type is one of: git, hg, quilt, stgit, topgit
  33         F: *Files* and directories wildcard patterns.
  34            A trailing slash includes all files and subdirectory files.
  35            F:   drivers/net/    all files in and below drivers/net
  36            F:   drivers/net/*   all files in drivers/net, but not below
  37            F:   */net/*         all files in "any top level directory"/net
  38            One pattern per line.  Multiple F: lines acceptable.
  39         X: *Excluded* files and directories that are NOT maintained, same
  40            rules as F:. Files exclusions are tested before file matches.
  41            Can be useful for excluding a specific subdirectory, for instance:
  42            F:   net/
  43            X:   net/ipv6/
  44            matches all files in and below net excluding net/ipv6/
  45         N: Files and directories *Regex* patterns.
  46            N:   [^a-z]tegra     all files whose path contains tegra
  47                                 (not including files like integrator)
  48            One pattern per line.  Multiple N: lines acceptable.
  49            scripts/get_maintainer.pl has different behavior for files that
  50            match F: pattern and matches of N: patterns.  By default,
  51            get_maintainer will not look at git log history when an F: pattern
  52            match occurs.  When an N: match occurs, git log history is used
  53            to also notify the people that have git commit signatures.
  54         K: *Content regex* (perl extended) pattern match in a patch or file.
  55            For instance:
  56            K: of_get_profile
  57               matches patches or files that contain "of_get_profile"
  58            K: \b(printk|pr_(info|err))\b
  59               matches patches or files that contain one or more of the words
  60               printk, pr_info or pr_err
  61            One regex pattern per line.  Multiple K: lines acceptable.
