That's right. The commits we're discussing here are (I believe): http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=75180df2ed467866ada839fe73cf7cc7d75c0a22 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=275a5d24bf56b2d9dd4644c54a56366b89a028f1 The later being the one returning EBUSY for the option mismatch and the former the addition of the "nosharecache" option.
