This commit looks large, but its really mostly a cleanup step. 1. introduce proper error handling for the return values of fcntl and the fbtl_posix_lock function 2. rename a parameter to more accurately reflect what it does 3. introduce an mca parameter in the fs/ufs component that allows to control what the level of locking the user would like to enforce 4. move the initialization of the fs_block_size parameter from fs/ufs into the common/ompio component. An fs component might be allowed to overwrite this value, but none of the actual fs components do that. Signed-off-by: Edgar Gabriel <egabriel@central.uh.edu>
