Subject: [PATCH 05/24] tools headers uapi: Sync asm-generic/mman-common.h with the kernel
Date: Tue, 1 Oct 2019 08:11:57 -0300 [thread overview]
Message-ID: <20191001111216.7208-6-acme@kernel.org> (raw)
In-Reply-To: <20191001111216.7208-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
To pick the changes from:
1a4e58cce84e ("mm: introduce MADV_PAGEOUT")
9c276cc65a58 ("mm: introduce MADV_COLD")
That result in these changes in the tools:

I.e. now when madvise gets those behaviours as args, it will be able to
translate from the number to a human readable string.
This addresses the following perf build warning:
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'
