X-Git-Tag: glibc-2.31~202 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aa9452a3b19e414678062c65ff7a2133482d62c3;p=thirdparty%2Fglibc.git Define MADV_COLD and MADV_PAGEOUT from Linux 5.4. Linux 5.4 adds constants MADV_COLD and MADV_PAGEOUT (defined with the same values on all architectures). This patch adds them to bits/mman-linux.h. Tested for x86_64. --- diff --git a/sysdeps/unix/sysv/linux/bits/mman-linux.h b/sysdeps/unix/sysv/linux/bits/mman-linux.h index d6755c59d5f..c0b11bfe248 100644 --- a/sysdeps/unix/sysv/linux/bits/mman-linux.h +++ b/sysdeps/unix/sysv/linux/bits/mman-linux.h @@ -87,6 +87,8 @@ # define MADV_DODUMP 17 /* Clear the MADV_DONTDUMP flag. */ # define MADV_WIPEONFORK 18 /* Zero memory on fork, child only. */ # define MADV_KEEPONFORK 19 /* Undo MADV_WIPEONFORK. */ +# define MADV_COLD 20 /* Deactivate these pages. */ +# define MADV_PAGEOUT 21 /* Reclaim these pages. */ # define MADV_HWPOISON 100 /* Poison a page for testing. */ #endif
