Subject: [PATCH 1/1 fyi] perf beauty: Sync UAPI linux/fs.h with kernel sources
Date: Wed, 4 Mar 2026 11:48:36 -0300 [thread overview]
Message-ID: <aahGRMUgnCLi2zUc@x1> (raw)
tldr; Just FYI, I'm carrying this on the perf tools tree.
Full explanation:
There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.
See further details at:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/include/uapi/README
To pick up changes from:
0e6b7eae1fded85f ("fs: add FS_XFLAG_VERITY for fs-verity files")
These are used to beautify fs syscall arguments, albeit the changes in
this update are not affecting those beautifiers.
This addresses these tools/perf build warnings:
Warning: Kernel ABI header differences:
diff -u tools/perf/trace/beauty/include/uapi/linux/fs.h include/uapi/linux/fs.h
Please see tools/include/uapi/README.
