From f4a2740a69d34b3ab0a7ecc7d4785b4b6b68e7cf Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 24 Feb 2016 18:44:10 +0000 Subject: [PATCH] Remove linux/fanotify.h configure test. Now we require Linux 3.2 or later kernel headers everywhere, the configure test for is obsolete; this patch removes it. Tested for x86_64. * sysdeps/unix/sysv/linux/configure.ac (linux/fanotify.h): Do not test for header. * sysdeps/unix/sysv/linux/configure: Regenerated. * config.h.in (HAVE_LINUX_FANOTIFY_H): Remove #undef. * sysdeps/unix/sysv/linux/tst-fanotify.c [!HAVE_LINUX_FANOTIFY_H]: Remove conditional code. [HAVE_LINUX_FANOTIFY_H]: Make code unconditional. --- ChangeLog | 8 +++++++ config.h.in | 3 --- sysdeps/unix/sysv/linux/configure | 42 ---------------------------------- sysdeps/unix/sysv/linux/configure.ac | 6 ----- sysdeps/unix/sysv/linux/tst-fanotify.c | 14 ------------ 5 files changed, 8 insertions(+), 65 deletions(-) diff --git a/ChangeLog b/ChangeLog index 578f1b6..ce9e24ee 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,13 @@ 2016-02-24 Joseph Myers + * sysdeps/unix/sysv/linux/configure.ac (linux/fanotify.h): Do not + test for header. + * sysdeps/unix/sysv/linux/configure: Regenerated. + * config.h.in (HAVE_LINUX_FANOTIFY_H): Remove #undef. + * sysdeps/unix/sysv/linux/tst-fanotify.c [!HAVE_LINUX_FANOTIFY_H]: + Remove conditional code. + [HAVE_LINUX_FANOTIFY_H]: Make code unconditional. + * sysdeps/unix/sysv/linux/configure.ac (LIBC_LINUX_VERSION): Define to 3.2.0.
