# This is a combination of merging up to 2.4.13 and cleaning up some
# mismatched rcs ids which had crept into the tree. It also makes the
# block device cache and the xfs metadata cache coherent - well almost
# coherent. The xfs super block and the log are written from special
# purpose buffers which are not part of the regular cache. 
# 
# Since unmount flushes and removes all cached data, the only time the
# inconsistency shows up is if you look at the block device while the
# fs is mounted. A consequence of this is that regression test number 17
# in the test suite will now fail - since it does precisely this.
# 
# I hope to fix the super block one at least at some point, this will
# make xfs_db on a running fs more useful, but the log may never be
# fully coherent with the block device interface...
