Subject: [PATCH v3 0/6] bootconfig: Add mixed subkeys and value under the same key
Date: Wed, 2 Jun 2021 15:24:22 +0900 [thread overview]
Message-ID: <162261506232.255316.12147562546699211199.stgit@devnote2> (raw)
Hi,
Here is the 3rd version of the series which updates bootconfig to
support mixed subkeys and a value under the same key.
Since the kernel cmdline accepts options like
"aaa.bbb=val1 aaa.bbb.ccc=val2", it is better that the bootconfig
also support it.
Here is the previous series:
https://lore.kernel.org/lkml/162157886618.78209.11141970623539574861.stgit@devnote2/
In this version, I rebased on top of the latest linus tree and
add the build error fix [1/6](*) and a cleanup patch [6/6].
(*) https://lore.kernel.org/lkml/162087519356.442660.11385099982318160180.stgit@devnote2/
Changes in v3
[1/6]:
- Added from separated thread. This is a fundamental fix.
[6/6]:
- New cleanup patch.
With this series, sub-keys and a value can co-exist under a parent key.
For example, following config is allowed.
foo = value1
foo.bar = value2
Note, since there is no syntax to put a raw value directly under a
structured key, you have to define it outside of the brace. For example,
foo {
bar = value1
bar {
baz = value2
qux = value3
}
}
Also, the order of the value node under a key is fixed. If there
are a value and subkeys, the value is always the first child node
of the key. Thus if user specifies subkeys first, e.g.
foo.bar = value1
foo = value2
In the program (and /proc/bootconfig), it will be shown as below
foo = value2
foo.bar = value1
Thank you,
