From: Eric Biggers <ebiggers@xxxxxxxxxx> '_require_xfs_io_command set_encpolicy -s' does not work as expected because the following in the output of 'xfs_io -c "help set_encpolicy"': -s LOG2_DUSIZE -- log2 of data unit size ... does not match the regex: "^ -s ([a-zA-Z_]+ )?--" ... because the 2 in the argument name LOG2_DUSIZE is not matched. Fix the regex to support digits in the argument name.
