Subject: [PATCH 00/15] linux system call fixes
Date: Thu, 20 Jun 2024 18:23:01 +0200 [thread overview]
Message-ID: <20240620162316.3674955-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb•de>
I'm working on cleanup series for Linux system call handling, trying to
unify some of the architecture specific code there among other things.
In the process, I came across a number of bugs that are ABI relevant,
so I'm trying to merge these first. I found all of these by inspection,
not by running the code, so any extra review would help. I assume some
of the issues were already caught by existing LTP tests, while for others
we could add a test. Again, I did not check what is already there.
The sync_file_range and fadvise64_64 changes on sh, csky and hexagon
are likely to also require changes in the libc implementation.
Once the patches are reviewed, I plan to merge my changes as bugfixes
through the asm-generic tree, but architecture maintainers can also
pick them up directly to speed up the bugfix.
Arnd
