The logic there which adds a dependency note to Sphinx cache
is not taking into account that the build dir may not be
the source dir. This causes a performance regression:
$ time make O=/tmp/foo SPHINXDIRS=admin-guide htmldocs
[OUTDATED]
Added: set()
Changed: {'abi-obsolete', 'abi-removed', 'abi-stable-files', 'abi-obsolete-files', 'abi-stable', 'abi', 'abi-removed-files', 'abi-testing-files', 'abi-testing', 'gpio/index', 'gpio/obsolete'}
Removed: set()
All docs count: 385
Found docs count: 385
real 0m11,324s
user 0m15,783s
sys 0m1,164s
To get the root cause of the problem (ABI files reported as changed),
I used this changeset:
diff --git a/Documentation/conf.py b/Documentation/conf.py
index e8766e689c1b..ab486623bd8b 100644
--- a/Documentation/conf.py
