Refactor all the places where we try to force new file data allocations to a specific xfs backing device so that we don't end up open-coding the same xfs_io command lines over and over.

# Tests xfs_growfs on the realtime volume to make sure none of it blows up.
|
|
# This is a regression test for the following patches:
|
|
#
|
|
# xfs: Set xfs_buf type flag when growing summary/bitmap files
|
|
# xfs: Set xfs_buf's b_ops member when zeroing bitmap/summary files
|
|
# xfs: fix realtime bitmap/summary file truncation when growing rt volume
|
|
# xfs: make xfs_growfs_rt update secondary superblocks
|
|
# xfs: annotate grabbing the realtime bitmap/summary locks in growfs
|
