- Use a fixed buffer of random bytes when random xattr values are in
effect. This eliminates the potential performance bottleneck of
reading from /dev/urandom for each file. This also allows us to
verify xattrs in random value mode.
- Show the rate of operations per second in addition to elapsed time
for each phase of the test. This may be useful for benchmarking.
- Set default xattr size to 6 so that verify doesn't fail if user
doesn't specify a size. We need at least six bytes to store the
leading "size=X" string that is used for verification.
- Allow user to execute just one phase of the test. Acceptable
values for -o and their meanings are:
1 - run the create phase
2 - run the setxattr phase
3 - run the getxattr phase
4 - run the unlink phase
