Revamp file locking Get rid of the semaphore implementation, no need to carry both. Add different locking modes (exclusive and readwrite) to enable a wider range of testing. Also combine lockfile and lockfile_batch, the latter is now a postfix option to the former. So to enable readers-excluding-writers locking mode with a lock batch count of 4, you would write: lockfile=readwrite:4 instead. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
