Subject: [PATCH 03/12] tools headers UAPI: Update tools's copy of mman.h headers
Date: Mon, 29 Jul 2019 18:14:50 -0300 [thread overview]
Message-ID: <20190729211456.6380-4-acme@kernel.org> (raw)
In-Reply-To: <20190729211456.6380-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
To pick up the changes from:
8aa3c927ec10 ("mm/mmap: move common defines to mman-common.h")
22fcea6f85f2 ("mm: move MAP_SYNC to asm-generic/mman-common.h")
0bf5f9492389 ("mm: fix the MAP_UNINITIALIZED flag")
To address the following perf build warnings:
Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman-common.h' differs from latest version at 'include/uapi/asm-generic/mman-common.h'
diff -u tools/include/uapi/asm-generic/mman-common.h include/uapi/asm-generic/mman-common.h
Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman.h' differs from latest version at 'include/uapi/asm-generic/mman.h'
diff -u tools/include/uapi/asm-generic/mman.h include/uapi/asm-generic/mman.h
That ends up just moving a bit the auto-generated code->string tables:
$ tools/perf/trace/beauty/mmap_flags.sh > before
$ cp include/uapi/asm-generic/mman.h tools/include/uapi/asm-generic/mman.h
$ cp include/uapi/asm-generic/mman-common.h tools/include/uapi/asm-generic/mman-common.h
$ tools/perf/trace/beauty/mmap_flags.sh > after
$ diff -u before after
