Commit based on the commit from wrs-switch-sw described below. userspace/libwr: improve locking of shmem Keep explicitly lock bit in the sequence variable as a LSB bit. This solution is backward compatible. The difference is only when shmem is lock twice. Before it was treated as unlocked, now still as a lock. Signed-off-by: Adam Wujek <adam.wujek@cern.ch>
