Otherwise, +the functions local_irq_enable()/local_irq_disable() will not +be defined and the prototype will be misdetected as the four +argument version. + +This change actually include 'linux/interrupt.h' which in turn +includes 'linux/irqflags.h' to be as generic as possible. + +Additionally, passing NULL as the function can result in a +gcc error because the on_each_cpu() macro executes it +unconditionally. To make the test more robust we pass the +dummy function on_each_cpu_func(). + +Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> +Closes #204 +--- + config/spl-build.m4 | 5 ++++- + 1 file changed, 4 insertions(+), 1 deletion(-) + +diff --git a/config/spl-build.m4 b/config/spl-build.m4 +index f710d8e..6e4afed 100644 +--- a/config/spl-build.m4 ++++ b/config/spl-build.m4 +@@ -1312,9 +1312,12 @@ dnl # + AC_DEFUN([SPL_AC_3ARGS_ON_EACH_CPU], [ + AC_MSG_CHECKING([whether on_each_cpu() wants 3 args]) + SPL_LINUX_TRY_COMPILE([ ++ #include <linux/interrupt.h> + #include <linux/smp.h> ++ ++ void on_each_cpu_func(void *data) { return; } + ],[ +- on_each_cpu(NULL, NULL, 0); ++ on_each_cpu(on_each_cpu_func, NULL, 0); + ],[ + AC_MSG_RESULT(yes) + AC_DEFINE(HAVE_3ARGS_ON_EACH_CPU, 1, +-- +1.7.10 + |
