[Xenomai] [RFC][PATCH] cobalt/synch: Do not drop PP on xnsynch_release if it wasn't committed

We must not try to drop the prio ceiling in the kernel if it wasn't committed yet. That could easily happen when using a prio-ceiling mutex to wait on a cond-var. This is not the most robust solution as it bases the decision on userspace controlled state which could be corrupted. Signed-off-by:

You can clone this: git://git.xenomai.org/ipipe-arm.git Then when you patch the kernel with scripts/prepare-kernel.sh leave --ipipe= blank or not add that argument. If you add --verbose to prepare-kernel you should see that the script detects the ipipe is already present in the tree and then
