From de3501d60fac6d194954e0ccc7bd297f53442b3e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 1 Jun 2022 14:45:48 +0000 Subject: [PATCH] Add MADV_DONTNEED_LOCKED from Linux 5.18 to bits/mman-linux.h Linux 5.18 adds a constant MADV_DONTNEED_LOCKED (defined in multiple header files, but with the same value on all architectures). Add this constant to bits/mman-linux.h. Tested for x86_64. --- sysdeps/unix/sysv/linux/bits/mman-linux.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/sysdeps/unix/sysv/linux/bits/mman-linux.h b/sysdeps/unix/sysv/linux/bits/mman-linux.h index 85bc4d3c3c..cb5ad30ef9 100644 --- a/sysdeps/unix/sysv/linux/bits/mman-linux.h +++ b/sysdeps/unix/sysv/linux/bits/mman-linux.h @@ -93,6 +93,8 @@ readable. */ # define MADV_POPULATE_WRITE 23 /* Populate (prefault) page tables writable. */ +# define MADV_DONTNEED_LOCKED 24 /* Like MADV_DONTNEED, but drop + locked pages too. */ # define MADV_HWPOISON 100 /* Poison a page for testing. */ #endif
