scripts/find-unused-docs: Fix massive false positives

2020-01-27T21:25:06+00:00

scripts/find-unused-docs.sh invokes scripts/kernel-doc to find out if a source file contains kerneldoc or not. However, as it passes the no longer supported "-text" option to scripts/kernel-doc, the latter prints out its help text, causing all files to be considered containing kerneldoc. Get rid of these false positives by removing the no longer supported "-text" option from the scripts/kernel-doc invocation.

checkpatch: reduce is_maintained_obsolete lookup runtime

2019-12-05T03:44:13+00:00

The is_maintained_obsolete function can be called twice using the same filename. This function spawns a process using get_maintainer.pl. Store the status of each filename when spawned and use the stored result to eliminate the spawning of unnecessary duplicate child processes.

Ignore all upper-case variants before and after SI units like mA, mV and uV so uses like RANGE_mA do not emit a CAMELCASE message.

A Fixes: lines in a commit message generally indicate that a previous commit was inadequate for whatever reason. The signers of the previous inadequate commit should also be cc'd on this new commit so update get_maintainer to find the old commit and add the original signers.

Now we just need to get maintainers to fill in the profiles... - A reworking of the parallel build setup to work better with a variety of systems (and to not take over huge systems entirely in particular). - The MAINTAINERS file is now converted to RST during the build. Hopefully nobody ever tries to print this thing, or they will need to load a lot of paper. - A script and documentation making it easy for maintainers to add Link: tags at commit time.
