Dear all,
Here is some in-detail explanation for clean-up patches to come.
# Motivation
There are various config files in the arch/*/configs/ directory, which have
been added at some point in the past, but have not been really maintained
with the various changes of config symbols that have been made, e.g.,
config symbol removals, renamings, splitting, etc.
This makes these configs refer to many outdated config symbols.
The script ./scripts/checkkconfigsymbols.py reports on
Many findings are referring to these unmaintained config files now. After
submitting a number of patches to clean up obsolete config symbols in
Kconfig files, Makefiles and some source files, it is time to clean up all
the config files as well.
The actual patches are created with a combination of simple bash scripting
and some manual assessment,
# Config Symbol Collection
First, scripts/checkkconfigsymbols.py is run, and then its output is
filtered down to the configs that are referenced in config files.
# Config Assessment
For each config symbol, we need to decide if it is to be removed, replaced
with another config or kept in the config file. Further, we record why we
came to that conclusion. For this decision, we automatically collect some
background information from the git history and if no git history is
available, search manually for patches that mention this config symbol.
The overall information can be aggregated in the following form:
config <config-symbol name>:
History:
- last defined in file <Konfig file> with kernel release <kernel-version>
- disappeared in commit <commit hash> ("<commit message>")
OR:
- never part of main-line kernel repository and patch search resulted in:
- config definition probably never made it to mainline, found no public record of a pending patch (no-patch-found)
- recent pending patches, to be integrated soon (recent)
- historic patches, never integrated (historic)
Decision:
remove, rationale: functionality/behavior is default. (rm-def)
remove, rationale: functionality/behavior was removed. (rm-rm)
remove, rationale: config never had an effect for mainline testing. (rm-oot)
keep, rationale: option recently added in config, config definition pending (keep-recent)
replace with <name of new config-symbol>, rationale: config was renamed (with no significant change of its semantics) (mv-<CONFIG_NAME>)
complex cleanup operation, rationale: config was split in a complex way and needs dedicated manual change (manual)
This information above then summarized below in two tables, using a few
abbreviations (see Appendix below).
For all config symbols that never existed in the repository, the following
one-line abbreviated form is used:
<config-symbol name>;<result-of-patch-search>(<pending-patch-references>);<decision-abbrev>
If the config existed in the repository, the following one-line abbreviated
form is used:
<config-symbol name>;<Kconfig file>;<commit reference>;<decision-abbrev>
# Patch Creation
Once all this information collected, the actual changes for each patch is
straight-forward and just needs to be submitted according to the
corresponding maintainer/subsystem to pick them up.
# Expected Effects (if at all)
The removal of non-existing config symbols should have no effect on any use
case. The fact that I spent some effort to identify the new symbols to
which historic config symbols have been renamed to, and then re-added the
new config symbol when deleting the old symbol, may have surprising effects
for some use cases, though.
Some functionality on some configs might have been inactive for so long
that bugs have creeped in, and with this change actually restoring the
initial intent of the original config, tests might reveal that some
things have been broken in the meantime.
It is not the patch series to blame, though, but then just requires to
understand what happened while testing on this config symbol was not
active. In the end, we are possibly just reactivating some testing that
was accidently by config changes switched off.
