[PATCH 038/115] xfs: support RT inodes in xfs_mod_delalloc

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Christoph Hellwig <hch@xxxxxx>

Source kernel commit: 7099bd0f243fa7511de6e95b0b8807ba7d3e5204

To prepare for re-enabling delalloc on RT devices, track the data blocks
(which use the RT device when the inode sits on it) and the indirect
blocks (which don't) separately to xfs_mod_delalloc, and add a new
percpu counter to also track the RT delalloc blocks.
