# FS QA Test No. 423

|
|
# Race scrubbing the inode record while appending to a file.
|
||
|
|
# This exposes a bug in xfs_bmap_count_blocks where we count delalloc
|
||
|
|
# extents for di_nblocks if the fork is in extents format, but we don't
|
||
|
|
# count them if the fork is in btree format.
