Add an --order switch to control section reordering. Default for --order is off. Change the default ordering to a slightly more sensible: M: Person acting as a maintainer R: Person acting as a patch reviewer L: Mailing list where patches should be sent S: Maintenance status W: URI for general information Q: URI for patchwork tracking B: URI for bug tracking/submission C: URI for chat P: URI or file for subsystem specific coding styles T: SCM tree type and location F: File and directory pattern X: File and directory exclusion pattern N: File glob K: Keyword - patch content regex Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

--section => new sorted MAINTAINERS file to write to (default: SECTION.new)
|

--order => Use the preferred section content output ordering (default: 0)
|
|
Preferred ordering of section output is:
|
|
M: Person acting as a maintainer
|
|
R: Person acting as a patch reviewer
|
|
L: Mailing list where patches should be sent
|
|
S: Maintenance status
|
|
W: URI for general information
|
|
Q: URI for patchwork tracking
|
|
B: URI for bug tracking/submission
|
|
C: URI for chat
|
|
P: URI or file for subsystem specific coding styles
|
|
T: SCM tree type and location
|
|
F: File and directory pattern
|
|
X: File and directory exclusion pattern
|
|
N: File glob
|
|
K: Keyword - patch content regex
|
|
|
|
If <pattern match regexes> exist, then the sections that match the
|
|
regexes are not written to the output file but are written to the
|
|
section file.
