When Dave outlined the requirements for PMEM_IMMUTABLE, it was very clear that metadata updates would not be possible. And would you really cosider this a barrier to marking dax fully supported?

We have ltp and xfstests. If you have some mkfs/mount options that you think should be tested, speak up. Beyond that, if it passes ./check -g auto and ltp, are we good? -Jeff -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
