Subject: [PATCH] tools headers UAPI: Sync linux/in.h copy with the kernel
sources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 1792a59eab9593de2eae36c40c5a22d70f52c026 upstream.
To pick the changes in:
321827477360934d ("icmp: don't send out ICMP messages with a source address of 0.0.0.0")
That don't result in any change in tooling, as INADDR_ are not used to
generate id->string tables used by 'perf trace'.
This addresses this build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/in.h' differs from latest version at 'include/uapi/linux/in.h'
