Christoph Hellwig 1df8d75030 xfs: make metabtree reservations global ... Currently each metabtree inode has it's own space reservation to ensure it can be expanded to the maximum size, mirroring what is done for the AG-based btrees. But unlike the AG-based btrees the metabtree inodes aren't restricted to allocate from a single AG but can use free space form the entire file system. And unlike AG-based btrees where the required reservation shrinks with the available free space due to this, the metabtree reservations for the rtrmap and rtfreflink trees are not bound in any way by the data device free space as they track RT extent allocations. This is not very efficient as it requires a large number of blocks to be set aside that can't be used at all by other btrees. Switch to a model that uses a global pool instead in preparation for reducing the amount of reserved space, which now also removes the overloading of the i_nblocks field for metabtree inodes, which would create problems if metabtree inodes ever had a big enough xattr fork to require xattr blocks outside the inode.
