# FS QA Test No. 521
#
# 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
#
