Currently, we are checking for sanlock_add_lockspace_timeout which is good for now. But in a subsequent patch we are going to use sanlock_write_lockspace (which sets an initial value for io timeout for sanlock). Now, there is no reason to check for both functions in sanlock library as the sanlock_write_lockspace was introduced in 2.7 release and the one we are currently checking for in the 2.5 release. Therefore it is safe to assume presence of sanlock_add_lockspace_timeout when sanlock_write_lockspace is detected. Moreover, the macro for conditional compilation is renamed to HAVE_SANLOCK_IO_TIMEOUT (as it now encapsulates two functions). Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
