Subject: [PATCH v2 0/4] string: Allow 2-argument strscpy()
Date: Mon, 5 Feb 2024 04:35:20 -0800 [thread overview]
Message-ID: <20240205122916.it.909-kees@kernel.org> (raw)
Hi,
v2:
- add strscpy_pad() coverage
- fix up ARCH=um to handle the renaming
- use __must_be_array() to validate sizeof() usage
v1: https://lore.kernel.org/all/20240131055340.work.279-kees@kernel.org/
Make it possible for strscpy() and strscpy_pad() to use 2 arguments,
making "sizeof(dst)" be the the default 3rd argument for the destination
size. This can make future usage much easier to read. Additionally allows
treewide changes to save a bunch of lines:
