[LU-2870] top level ./configure always runs ldiskfs/configure despite of --disable-ldiskfs-build

Thu, 9 Jan 2020 06:30:29 +0000

The top level ./configure script always runs ldiskfs/configure despite of --disable-ldiskfs-build or --disable-server.

If I'm building for clients, it does not make sense to me to run ldiskfs/configure, but maybe there's things I don't see yet. It seems that ldiskfs/configure is always called as long as the ldiskfs/ subdir exists, in build/autoconf/lustre-build-ldiskfs.m4:

if test -e "$PWD/ldiskfs"; then
LDISKFS_DIST_SUBDIR="ldiskfs"
AC_SUBST(LDISKFS_DIST_SUBDIR)
AC_CONFIG_SUBDIRS("ldiskfs")
fi

If I commented out the AC_CONFIG_SUBDIRS() line, ldiskfs/configure is no longer run and everything seemed to build just fine.

BTW, it should be a "test -d" instead of "test -e".
