The RT rwsem implementation was changed to allow multiple readers as of the 4.9.20-rt16 patch set. This results in a build failure because the existing implementation was forced to directly access the rwsem structure which has changed. While this could be accommodated by adding additional compatibility code. This patch resolves the build issue by simply assuming the rwsem can never be upgraded. This functionality is a performance optimization and all callers must already handle this case. Converting the last remaining use of __SPIN_LOCK_UNLOCKED to spin_lock_init() was additionally required to get a clean build. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #7589
