When trying to build zfs-kmod against a a 3.13.[0|1|2] kernel, spl works
fine, but zfs fails. It looks like the issue is that the configure script
isn't doing quite the right check for bdi_setup_and_register, so
HAVE_BDI_SETUP_AND_REGISTER doesn't get defined, and then there's a
mismatch in the definitions between zfs and the kernel source. The
offending bit in the configure log looks to be:
configure:17996: checking whether bdi_setup_and_register() is available
configure:18024: cp conftest.c build && make modules -C /usr/src/linux
EXTRA_CFLAGS=-Werror
M=/var/tmp/portage/sys-fs/zfs-kmod-0.6.2-r3/work/zfs-zfs-0.6.2/build
/var/tmp/portage/sys-fs/zfs-kmod-0.6.2-r3/work/zfs-zfs-0.6.2/build/conftest.c:
In function 'main':
/var/tmp/portage/sys-fs/zfs-kmod-0.6.2-r3/work/zfs-zfs-0.6.2/build/conftest.c:91:25:
error: ignoring return value of 'bdi_setup_and_register', declared with
attribute warn_unused_result [-Werror=unused-result]
bdi_setup_and_register(NULL, NULL, 0);
^
Anyone else seeing this?
