the files under /80211 calls kernel-doc script 207 times, one for each
single function and doc chapter. Due to that, it takes a lot of time
handling it:
$ touch Documentation/driver-api/80211/*rst && time make SPHINXDIRS=driver-api/80211 htmldocs
...
real 0m22,928s
user 0m21,644s
sys 0m1,334s
Reduce the build time by doing only one kernel-doc call
per functions that belong to the same group. With that, there's now
50 calls to kernel-doc, which makes the build time for those docs
62% faster:
$ touch Documentation/driver-api/80211/*rst && time make SPHINXDIRS=driver-api/80211 htmldocs
...
real 0m8,666s
user 0m8,084s
sys 0m0,642s
As a side effect, it should now be easier to add newer
functions, as there's no need to repeat the kernel-doc
pattern.
Measurements made on a NUC8i7HNK machine with lots of ram
and a fast SSD disk with Sphinx 3.2.1.
